Question

Identify the reaction in which the hybridization of the underlined atom is changed

• A. $\underline{N}H_3(g)+H_2O(l)\rightarrow NH_4^{+}+OH^{-}$
• B. $\underline{POCl_3}+3H_2O\rightarrow H_3PO_4+3HCl$
• C. $\underline{SO_2}(g)+H_2O(l)\rightarrow H_2SO_3$
• D. $\underline{P}Cl_3+3H_2O\rightarrow H_3PO_3+3HCl$

Hint:

Whenever hybridization questions are asked, first calculate the steric number: \[ \text{Steric Number}= \text{Bond Pairs}+\text{Lone Pairs} \] A change in steric number usually indicates a change in hybridization.

Answer 1
