Zn / Hg , HCl (Clemmensen reduction) is acid catalysed.So, the dehydration will also take place along with the conversion of (>C=O)group to (- CH 2-) groupSo the answer is (b)

Q. The appropriate reagent for the following transformation is:

$Z n (H g), H Cl$

$N H_{2} N H_{2}, O H$

$H_{2} / N i$

$N a B H_{4}$

a. $Z n / H g, H Cl$ (Clemmensen reduction) is acid
catalysed.So, the dehydration will also take place along with the conversion of $(> C = O)$ group to $(- C H_{2} -)$ groupSo the answer is (b)

Q. The appropriate reagent for the following transformation is:

Zn(Hg),HCl

NH2​NH2​,OH

H2​/Ni

NaBH4​

a. Zn/Hg,HCl (Clemmensen reduction) is acid catalysed.So, the dehydration will also take place along with the conversion of (>C=O)group to (−CH2​−) groupSo the answer is (b)

$Z n (H g), H Cl$

$N H_{2} N H_{2}, O H$

$H_{2} / N i$

$N a B H_{4}$

a. $Z n / H g, H Cl$ (Clemmensen reduction) is acid
catalysed.So, the dehydration will also take place along with the conversion of $(> C = O)$ group to $(- C H_{2} -)$ groupSo the answer is (b)
