Hydrogen molecule differs from chlorine molecule in which of the following respect?
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 from intermoelcular hydrogen bonds but chlorine molecule can not
D
Hydrogen molecule cannot participate in coordination bond formation but chlorine molecule can
Correct option is D. Hydrogen molecule cannot participate in coordination bond formation but chlorine molecule can
Chlorine has a lone pair of electrons and vacant d-orbitals, thus they can take part in coordinate covalent bond. Hydrogen molecule does not have a lone pair of electrons. So it will not take part in the coordinate bond
Both chlorine and hydrogen gas are non-polar molecules as they are bonded to the same element and have same electronegativity.
