Question

Which of the following substances has dipole moment more than zero ?

• A. Water
• B. Methane
• C. Carbon disulphide
• D. Benzene

Answer 1

The correct option is A Water

Explanation : Water has dipole moment of more than zero due to the presence of Oxygen which has a partial negative charge ( ${\delta }^{-}$ ) and the presence of hydrogens which have a partial positive charge ( ${\delta }^{+}$ ). Due to the presence of this charge seperation, water has a dipole moment of more than zero.
