Current Question (ID: 8100)

Question:

$\text{The strongest hydrogen bond present among the following is-}$

Options:

1. $\text{O}—\text{H}\cdots\text{S}$
2. $\text{S}—\text{H}\cdots\text{O}$
3. $\text{F}—\text{H}\cdots\text{F}$
4. $\text{F}—\text{H}\cdots\text{O}$

Solution:

$\text{HINT: HF has the strongest H-bonding}$ $\text{Explanation:}$ $H—\text{bonding order: } \cdots H—F >\cdots H—O >\cdots H—N$ $\text{The strongest hydrogen bond is in hydrogen fluoride because the power of the hydrogen bond is directly proportional to the electronegativity of the atom. The electronegativity } \propto \frac{1}{\text{atomic size}}.$ $\text{So, fluorine has maximum electronegativity and minimum atomic size.}$ $\text{Hence, it can show maximum hydrogen bonding.}$
