• # question_answer Which of the following has the lowest bond angle? A) ${{H}_{2}}O$                     B) $C{{H}_{4}}$         C)   ${{H}_{2}}S$         D)   $N{{H}_{3}}$

The bond angles of the given molecules are as follows $C{{H}_{4}}-{{109}^{o}}-28'$ $N{{H}_{3}}-{{107}^{o}}$ ${{H}_{2}}O-{{104.5}^{o}}$ ${{H}_{2}}S-{{92}^{o}}$ Hence, the correct option is (c).
