Question

`C_(6)H_(5)-CH=CHCHO overset((X))rarr C_(6)H_(5)=CHCH_(2)OH`
In the above sequence (X) can be:
A. `H_(2)//Ni`
B. `NaBH_(4)`
C. `K_(2)Cr_(2)O_(7)//H^(+)`
D. Both (a) and(b)

Answer 1

Correct Answer - B
`Ph-CH=CH-CHO`
`overset(NaBH_(4))rarr Ph-CH=CH-CH_(2)OH`
`NaBH_(4)` does reduce `(C=C)` and `(C-=C)` bonds.
