question_answer 1)

  Which of the following angle corresponds to \[s{{p}^{2}}\]hybridisation? (a)\[90{}^\circ \]                                               (b) \[120{}^\circ \]                           (c)\[180{}^\circ \]                                             (d) \[109{}^\circ \]

Answer:

  (b)\[s{{p}^{2}}\]-hybridisation assumes triangular planar geometry in which each angle is of\[120{}^\circ \].
