Trick to Remember Some bi-carboxylic acid
1.Oxalic acid-0 carbon- Oh
2.Maleic acid- 1 carbon- My
3.Succinic acid- 2 carbon- Sun
4.Glutamic acid-3 carbon-Go
5.Adipic acid- 4 carbon- And
6.Palmitic acid- 5 carbon- play
Number of carbons refers number of -CH2 group between two COOH group.
For e.g HOOC-COOH (OXALIC ACID) there is no CH2 group between carboxyl. Maleic acid is HOOC-CH2-COOH there is one CH2 group in betwen. This is how you can remember some bi-carboxylic acid.
