Current Question (ID: 20997)

Question:

$\text{How many of the following compounds exhibit hydrogen bonding?}$ $\text{i.}$ \ \text{Benzene} \ \text{ii.}$ \ \text{H}_2\text{O} \ \text{iii.}$ \ \text{CH}_3\text{OH} \ \text{iv.}$ \ \text{HF} \ \text{v.}$ \ \text{NH}_3 \ \text{vi.}$ \ \text{Phenol with NO}_2 \ \text{vii.}$ \ \text{Phenol with NH}_2 \ \text{viii.}$ \ \text{C}_2\text{H}_6$

Options:

1. $\text{Two}$
2. $\text{Four}$
3. $\text{Six}$
4. $\text{Five}$

Solution:

$\text{The system having suitable electropositive pole H and suitable electronegative pole can show H-bonding.}$ $\text{Suitable positive pole H: F-H, O-H, >N-H, suitable negative pole:}$ $\text{Electronegative element F, O, N with sufficient negative charge.}$ $\text{Hence H}_2\text{O}, \text{CH}_3\text{OH}, \text{HF and NH}_3 \text{can show intermolecular H bonding}$ $\text{and phenol with NO}_2 \text{and phenol with NH}_2 \text{can show intermolecular H bonding.}$
