Question

The molecule which does not exhibit strong intermolecular hydrogen bonding is:

• A. Methylamine
• B. Diethyl ether
• C. Acetic acid
• D. Ethanol

Answer 1

The correct option is B Diethyl ether

The molecule which does not exhibit strong hydrogen bonding is diethyl ether $C{H}_3-O-C{H}_3$
Hydrogen bonding is possible when $H$ atom is attached to an electronegative atoms eg. $N,O\text{or}F$.
In methylamine, $H$ is attached to $N$ atom.
In diethyl ether, $H$ is attached to $C$ atom and hence can not show hydrogen bonding.
In acetic acid and glucose, $H$ is attached to electronegative $O$ atom and show hydrogen bonding.
In ethanol and acetic acid, $H$ is attached to electronegative $O$ atom and show hydrogen bonding.
Hence, b is the correct option.
