    Among the following which one is a linear molecule having zero dipole moment?

    A) \[{{H}_{2}}O\]

    B) \[HCl\]

    C)  \[C{{O}_{2}}\]

    D)  \[{{H}_{2}}S\]

    Correct Answer: C

    Solution :

     \[\text{C}{{\text{O}}_{\text{2}}}\]is a linear molecule. It has zero dipole moment due to its symmetrical structure. \[O=C=O;\,\,\theta ={{180}^{o}}\]and \[\mu =0\]
