Question

rate of decarboxylation for soda lime will be maximum in -
( 1) Acentic acid
(2) 3-Butenoic acid
(3) 3-oxobutanoic acid
(4) pent-2-ynoic acid

Answer 1

1-acetic acid...... but not sure....

Answer 2

Hey dear,

● Answer -
(1) Acetic acid

● Decarboxylation of carboxylic acids -
- When a carboxylic acid is heated with soda lime, -COOH group is removed from it, this is called decarboxylation.
- Decarboxylation occurs faster if carboxylic group is attached to terminal carbon.
- As acetic acid is a straight chain carboxylic acid, its decarboxylation is maximum.
CH3COOH + 2NaOH ---> CH4 + Na2CO3 + H2O

Hope this helps you...
