Indicate correct synthesis of carboxylic acid from organometallic compound.

A

`CH_(3)MgBr overset(CO_(2))toX overset(H_(3)O^(+))to`

B

`CH_(3)MgBr underset((ii)CO_(2))overset((i)H_(3)O^(+))to`

C

`CH_(3)overset(O)overset(||)C CH_(2)CH_(2)MgBr underset((ii) LiAlH_(4))overset((i) H_(2)O)to`

D

All of the above

Text Solution

Verified by Experts

The correct Answer is:
A
a) `CH_(3)MgBr overset(CO_(2)//H_(2)O^(+))to CH_(3)COOH`
b) `CH_(3)MgBr overset(H_(2)O^(+))to CH_(4)overset(CO_(2))to` no reaction. Grignard reagent is decomposed by `H_(3)O^(+)` in first step.
c) Carboxyl group and grignard reagent both are present in same substance.
