Comparison Between Sigma And Pi Bond :
Sigma Bond π
1. Formed by axial overlapping
2. Involves s-s, s-p, p-p (axial) & hybrid orbitals
3. Extent of overlapping is more so stronger
4. Free rotation around s bond is possible
5. Hybridized or unhybridized orbital forms s bond
6. Independent existence of s-bond.
Pi Bond π
1. Formed by side by side overlapping
2. Involve p-p, p-d & d-d orbital
3. Extent of overlapping is less so weaker
4. Free rotation around p bond is not possible
5. Hybridized orbital never forms pi bond
6. No independent existence.

πβ»οΈAtoms & Moleculesβ»οΈπ
Around 500 BC, an Indian Philosopher Maharishi Kanad, first time postulated the concept of indivisible part of matter and named it βpramanu.β
In 1808, John Dalton used the term βatomβ and postulated the atomic theory to the study of matter.
π Daltonβs Atomic Theory
βAccording to Daltonβs atomic theory, all matter, whether an element, a compound or a mixture is composed of small particles called atoms.
βAccording to Daltonβs atomic theory, all matters, whether they are elements, compounds, or mixtures, are composed of small particles known as atoms.
π Salient features of Daltonβs Atomic Theory
βAll matter is made of very miniscule particles known as atoms.
βAtom is an indivisible particle, which cannot be created or destroyed through chemical reaction.
βAll atoms of an element are identical in mass and chemical properties whereas, atoms of different elements have different masses and chemical properties.
βTo form a compound, atoms are combined in the ratio of small whole numbers.
βIn a given compound, the relative number and kinds of atoms are constant.
π Atomic Mass
βThe mass of an atom of a chemical element; it is expressed in atomic mass units (symbol is u).
βThe atomic mass is roughly equivalent to the number of protons and neutrons present in the atom.
βOne atomic mass unit is a mass unit equal to the exactly one-twelfth (1/12th) the mass of one atom of carbon-12 and the relative atomic masses of all elements have been calculated with respect to an atom of carbon-12.
π Molecule
βThe smallest particle of an element or a compound, which is capable to exist independently and shows all the properties of the respective substance.
βA molecule, normally, is a group of two or more atoms which are chemically bonded together.
βAtoms of the same element or of different elements can join (with chemical bond) together to form molecules.
βThe number of atoms that constitute a molecule is known as its atomicity.
π Ion
βA charged particle is known as ion; it could be either negative charge or positive charge.
βThe positively charged ion is known as a βcationβ.
βThe negatively charged ion is known as an βanion.β
π Chemical Formulae
βA chemical formula of a compound demonstrations its constituent elements and the number of atoms of each combining element.
βThe chemical formula of a compound is the symbolic representation of its Composition.
βThe combining capacity of an element is known as its βvalency.β
π Molecular Mass
βThe molecular mass of a substance is calculated by taking the sum of the atomic masses of all the atoms in a molecule of respective substance. For example, the molecular mass of water is calculated as β
βAtomic mass of hydrogen = 1u
βAtomic mass of oxygen = 16 u
βThe water contains two atoms of hydrogen and one atom of oxygen.
βMolecular Mass of Water is = 2 Γ 1+ 1Γ16 = 18 u (u is the symbol of molecular mass).
π Formula Unit Mass
The formula unit mass of a substance is calculated by taking the sum of the atomic masses of all atoms in a formula unit of a compound.
π Avogadro Constant or Avogadro Number
βAvogadro was an Italian scientist who had given the concept of Avogadro Number (also known as Avogadro Constant).
βThe number of particles (atoms, molecules, or ions) present in 1 mole of any substance is fixed, and its value always calculated as 6.022 Γ 1023.
βIn 1896, Wilhelm Ostwald had introduced the concept of βmole;β however, mole unit was accepted to provide a simple way of reporting a large number in 1967.
π Law of Conservation of Mass
During a chemical reaction, sum of the masses of the reactants and products remains unchanged, which is known as the βLaw of Conservation of Mass.β
π Law of Definite Proportions
In a pure chemical compound, its elements are always present in a definite proportion by mass, which is known as the βLaw of Definite Proportions.β

π Important One Liners on Electric Charges π
------------------------------------------------------------------------
β«οΈ If an object is attracted by another charged body, the first object may be oppositely charged or not charged because we know both an uncharged object and an oppositely charged object are attracted by another charged object.
β«οΈ If an object is positively charged it loses some of its electrons. The mass of an electron is 9.11*10^-31 kg. So, if a positively charged body loses βnβ number of electrons, it mass decrease by the amount n*9.11E^-31kg.
β«οΈ Though gold is a costly metal it is used in electroscope because of the property malleability. This means very thin and light sheets can be formed from gold simply by hammering or rolling and hence the deflection of the light gold plates increases.
β«οΈ The divergence of the plates of the Gold-leaf oscilloscope depends only on the presence of a charge, not on the quality of charge i.e. positive or negative. So, if the charge changes from positive to negative and vice versa the degree of divergence of the plates remains the same.
β«οΈ The same charges repel each other. So, they try to maintain maximum distance from each other and hence they try to remain at the outer surface of an object. If the charge remains on the inner surface or throughout the body, they will repel each other with greater force.
β«οΈ The human body is a good conductor and hence the charge produced by friction flew through his body to the ground. We can tackle the problem simply by holding the brass rod with the help of some insulated holder.
β«οΈ If the apparatus is initially in contact with some positively charged body and then comes in contact with another β«οΈ charged body and if the divergence increases we can deduce that the second body is also positively charged. If the divergence decreases then the second body must be negatively charged.
β«οΈ According to electrostatic series, glass is situated above silk. So, if the glass is rubbed with silk, the positive charge on glass and negative charge on silk is produced. Similarly, we can predict what is the nature of charge if we rub two di-electric substances together.
β«οΈ 1 Coulomb means 3*10^9 Electro Static Unit of charge. Coulomb and ESU are two different units of charge and their conversion formula is necessary. Coulomb is the unit of charge in the SI system and esu is the unit of charge in the CGS system.
β«οΈ The two spheres are oppositely charged by the same amount. So if they come in contact, both of their charges are neutralized. So they become uncharged and donβt attract or repel each other.

BIOTECH SHORT NOTES
Biotechnology essentially deals with industrial scale production of biopharmaceuticals and biologicals
. The applications of biotechnology include therapeutics, diagnostics, genetically modified crops for agriculture, processed food, bioremediation, waste treatment and energy production.
2. Biotechnology have the following three critical research areas:
(i) To provide the best catalyst in the form of improved organism, usually a microbe or pure enzyme.
(ii) To create optimal conditions through engineering for a catalyst to act.
(iii) Downstream processing technologies to purify the protein/organic compound.
