Current Question (ID: 8104)

Question:

$\text{Which molecule is least likely to form hydrogen bonds?}$

Options:

1. $\text{NH}_3$
2. $\text{H}_2\text{NOH}$
3. $\text{HF}$
4. $\text{CH}_3\text{F}$

Solution:

$\text{HINT: } \text{CH}_3\text{F} \text{ does not contain H-bonds.}$ $\text{Explanation:}$ $\text{When hydrogen atoms are attached to an electronegative atom to form a covalent bond, the electrons of the covalent bond are shifted towards the more electronegative atom. This partially positively charged hydrogen atom forms a bond with the other more electronegative atom. This bond is known as a hydrogen bond and is weaker than the covalent bond.}$ $\text{In H-bonding, a hydrogen atom should be attached to a more electronegative atom.}$ $\text{In } \text{CH}_3\text{F}\text{, hydrogen bonding did not occur because hydrogen is attached to a carbon atom and carbon atom is not an electronegative element.}$
