JEE Main Chemistry question

Not in JEE Main or NEET syllabus

Hydrogen molecule differs from chlorine molecule in the following respect. [RPET 2010]

(A)Hydrogen molecule is 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 coordinate bond formation but chlorine molecule canCorrect

Answer: (D)

Solution

Both H and Cl are homonuclear diatomic molecules and hence both are non-polar, ruling out (A) and (B); and it is chlorine (not hydrogen) that forms intermolecular hydrogen bonds in certain contexts, not the reverse, so (C) is also incorrect.
