    The hybridization state of carbon atoms in the product formed by the reaction of ethyl chloride with aqueous KOH is:

    A)  \[sp\]                                  

    B)  \[s{{p}^{2}}\]

    C)  \[s{{p}^{3}}\]                                   

    D)  \[s{{p}^{3}}d\]

    Correct Answer: C

    Solution :

                     The function of aqueous KOH is to convert halogen to hydroxy group. So, ethyl chloride reacts with aq. KOH to give \[{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}\text{OH}\]as: \[\begin{matrix}    {{C}_{2}}{{H}_{5}}  \\    \underset{Aq.}{\mathop{O\overset{+}{\mathop{H}}\,}}\,  \\ \end{matrix}\xrightarrow{{}}\underset{\text{Ethyl}\,\text{alcohol}}{\mathop{{{C}_{2}}{{H}_{5}}OH}}\,+KCl\] In \[{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}\text{OH}\]all the four valencies of carbon are single bonded. So, hybridization of carbon atom in \[{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}\text{OH}\]is \[\text{s}{{\text{p}}^{3}}.\]
