`R-CH_(2)-CH_(2)OH` can be converted into `RCH_(2)CH_(2)COOH` the correct sequence of reagent is:

A

`PBr_(3), KCN, H_(3)O^(+)`

B

`PBr_(3), KCN, H_(2)//Pt`

C

`KCN, H_(3)O^(+)`

D

`PBr_(3), H_(3)O^(+)`

Text Solution

Verified by Experts

The correct Answer is:
A
`R CH_(2)CH_(2)-OH overset(PBr_(3))underset(-H_(3)PO_(3))rarr R CH_(2)CH_(2)Br`
`R CH_(2)CH_(2)Br overset(KCN)underset(-KBr) rarr R CH_(2)CH_(2)CN`
`R CH_(2)CH_(2)CN overset(H_(3)O^(+))rarr R CH_(2)CH_(2)COOH`
