Question

Match the following substances with their intermolecular forces:

List-I	List-II
(i) $C{H}_4$	(p) Dispersion Force
(ii) $NC{l}_3$	(q) Hydrogen Bonding
(iii) $C_4{H}_{9}OH$	(r) Dipole-dipole

• A. (i) - (p), (ii) - (q), (iii) - (r)
• B. (i) - (q) , (ii) - (p) , (iii) - (r)
• C. (i) - (p) , (ii) - (r), (iii) - (q)
• D. (i) - (r) , (ii) - (q) , (iii) - (p)

Answer 1

The correct option is C (i) - (p) , (ii) - (r), (iii) - (q)

$C{H}_4$ is non-polar because there is no net dipole moment.
$NC{l}_3$ is polar but it doesn't show H-bonding.
$C_4{H}_{9}OH$ is polar and shows H-bonding.
