Which is the best reagent for the following transformation?
`CH_(3)-C-=C-CH_(2)-overset(O)overset(|)(C)-Cl to CH_(3) -C-=C-CH_(2)-overset(O)overset(||)(C)-H`

A

`Li[{CH_(3)}_(3)AIH]//78^(@)C`

B

`Pd//BaSO_(4)//H_(2)`

C

`LiAIH_(4) then CrO_(3)-H_(2) SO_(4)`

D

`NaBH_(4) then CrO_(3)-H_(2) SO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
A
Given hydride is very bulky, brings about reduction at acid chloride and that too up to aldehyde level but not at olefinic triple bond.
