Question

what happens when benzoic acid is heated with soda lime?

Answer 1

HEYA!!

if you heat sodium ethanoate with soda lime, you get methane gas formed: This reaction can be done with certain carboxylic acids themselves. For example, benzene can be made by heating soda lime with solid benzoic acid (benzenecarboxylic acid), C6H5COOH.

Answer 2

Answer:

on heating with soda lime carboxylic acids lose their COOH group and produce a small alkane plus sodium carbonate.

CH3CH2COOH+2NaOH gives rise to CH3CH3+Na2CO3+H2O
