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.
