  • question_answer \[Cl-C-Cl\] angle in 1, 1, 2, 2 - tetrachloroethene and tetrachloromethane respectively are about [IIT-JEE 1988]

    A) \[{{120}^{o}}\] and \[{{109.5}^{o}}\]

    B) \[{{90}^{o}}\] and \[{{109.5}^{o}}\]

    C) \[{{109.5}^{o}}\] and \[{{90}^{o}}\]

    D) \[{{109.5}^{o}}\] and \[{{120}^{o}}\]

    Correct Answer: A

    Solution :

    \[120{}^\circ \] and \[109.5{}^\circ \] \[\underset{\text{Bond angle }=\text{ 12}{{\text{0}}^{\text{o}}}}{\mathop{\underset{s{{p}^{2}}\text{-hybridization}}{\mathop{Cl-\underset{Cl}{\mathop{\underset{|}{\mathop{C}}\,}}\,=\underset{Cl}{\mathop{\underset{|}{\mathop{C}}\,}}\,-Cl}}\,}}\,\]
