MCQ

Which contains strongest $H - $bond

A
$O - H.....S$
B
$S - H.....O$
✓
$F - H.....F$
D
$O - H.....O$

✓

Answer

Correct option: C.

$F - H.....F$

(c)The strongest hydrogen bond is in hydrogen fluoride because the power of hydrogen bond $\infty$ electronegativity of atom and

electronegativity $ \propto \frac{1}{{{\rm{atomic}}\,{\rm{size}}}}$

So fluorine has maximum electronegativity and minimum atomic size.
