Question

RCH₂OH -> RCH₂I
transform this ​

Answer 1

Explanation:

Aldehydes and ketones are reduced to the corresponding alcohols by addition of hydrogen in the presence of catalysts (catalytic hydrogenation). It is also prepared by treating aldehydes and ketones with sodium borohydride (NaBH

) or lithium aluminium hydride (LiAlH

).

The reaction of RMgX with any aldehyde other than methanal gives secondary alcohols not the primary alcohols.

RCHO+RMgX→R−CH(OMgX)−R
