Least voltage hydrogen halide is
Options
(a) HF
(b) HCl
(c) HI
(d) HBr
Correct Answer:
HI

As the size of halogen atom increases, the boiling point of hydrogen halides increases. However, HF has the highest boiling point among the hydrogeno halides because of H-bonding and
Boiling point ∞ 1 / volatility
Thus, HF is least volatile among hydrogen halides.
