1622021328_chemistry 27.JPG

$LiAlH_{4} in (C_{2}H_{5})_{2}O$

$BH_{3}$ in THF

$NaBH_{4}$ in

$C_{2}H_{5}OH$

D) Raney

$Ni/H_{2}$ in THF

Option C

Only -CHO group is to be reduced to -CH₂OH

It can be done using $NaBH_{4}$ in $C_{2}H_{5}OH$

(a) $LiAlH_{4} / (C_{2}H_{5})_{2}O$ reduces I,II and III into - $CH_{2}OH$ , and IV into diol.

(b) $BH_{3}$ / THF show same properties as (a)

(d) Raney nickel, same as (a) and (b) thus (c) is correct reagent
