Question

(Q.161) The hydride ion transfer takes place at each step in the
reduction done by using 1 mark
(a H2 in the presence of Nickel.
(b Sodium in the presence of ethanol.
(c LiAlH4.
d Zn and NH4OH.​

Answer 1

Explanation:

Hydride ion transfer

• The first partial reaction, the hydride transfer, requires the cofactor nicotinamide adenine dinucleotide phosphate (NADPH). NADPH serves as a source for two electrons and a proton (H(+)), the equivalent of a hydride anion, H(-). Hydride transfer reactions play a key role in many biological systems.
