In which of the following processes hybridization is not affected?

A
$NH _3+ H _2 O \longrightarrow NH _2 OH$
B
$LiH + AlH _3 \longrightarrow LiAlH _4$
C
$PCl _5(s) \xrightarrow{\text { melt }} PCl _4^{+}+ PCl _6^{-}$
D
$BeF _2(g) \xrightarrow{\text { Hoar frosting }} BeF _2(s)$

Answer

A. $NH _3+ H _2 O \longrightarrow NH _2 OH$
Explanation:
In $NH _3+ H _2 O \longrightarrow NH _2 OH$ Process hybridization is not affected. In this process both the nitrogen in the reactant and product are in $sp ^3$ hybrid state.
i. $\underset{s p^3 d}{P C l_5} \longrightarrow \underset{s p^3}{ PCl _4^{+}}+\underset{s p^3 d^2}{ PCl _6^{-}}$
ii. $\underset{s p^2}{ AlH _3} \longrightarrow \underset{s p^3}{ AlH _4^{-}}$
iii. $\underset{s p}{B e F_2} \longrightarrow \underset{s p^3}{B e F_2(s)}$
iv. $\underset{s p^3}{ NH _3} \longrightarrow \underset{s p^3}{ NH _4^{+}}$
