Question

Match the following substances with types of inter molecular forces:

List-I	List-II
a) $C{H}_4$	i) London, dipole-dipole
b) $CHC{l}_3$	ii) London
c) $C_4{H}_{9}OH$	iii) London, dipole-dipole, hydrogen bonding.

• A. a-ii, b-i, c-iii
• B. a-i, b-ii, c-iii
• C. a-iii, b-i, c-ii
• D. a-iii, b-ii, c-i

Answer 1

Answer: (A)

a-ii, b-i, c-iii

$C{H}_4$ is not polar because there is not much difference between the electronegativity of Hydrogen and Carbon.
$CHC{l}_3$ is polar but it doesn't show H-Bonding.
$C_4{H}_{9}OH$ is polar and shows H-Bonding.
