Question

no. of isomeric sodium salt that will be required to obtain neopentane

Answer 1

Answer

When sodium salt of carboxylic acid is heated with soda lime then we get a less carbon alkane. The reaction is called decarboxylation.

RCOONa+NaOH ^CaO,∆-> RH + Na₂CO₃

There is only one sodium salt to obtaine neopentane via carboxylarion:

CH₃C(CH₃)₂CH₂COONa

The reaction is:

CH₃C(CH₃)CH₂COONa + NaOH -> C(CH₃)₄ + Na₂CO₃
