Hydrogen molecule differs from chlorine molecule in the following respect:

Options

A. Hydrogen moleculeis non-polar but chlorine molecule is polar
B. Hydrogen molecule is polar while chlorine molecule is non-polar
C. Hydrogen molecule can form intermolecular hydrogen bonds but chlorine molecule does not
D. Hydrogen molecule cannot participate in coordination bond formation but chlorine molecule can

Answer

D

Explanation

Hydrogen molecule cannot participate in coordination bond formation but chlorine molecule can because there is no unshared pair of electrons in hydrogen molecule `(H_(2))` whereas chlorine molecule has six unshared electron pairs as shown below.

Coordinate bond is formed by sharing of an electron pair between the atoms where the shared pair of electrons is contributed by only one of the atom.
