(a) As we move down the group, conjugate base stability increases due to larger size of ion so strength of acid increases.
order is HI > HBr > HCl > HF.
(b)As we move down the group, conjugate base stability increases due to larger size of ion so strength of acid increases.
order is HI > HBr > HCl > HF.
(c) HF has maximum H-bonding due to highes electronegativity so HF have maximum boiling point.
(d) HF is the acid that attacks glass.
(e) Due to maximum electronegativity, HF have maximum dipole moment.
(f) Some of the more important nonaqueous solvents are NH3,HF,SO2,SOCl2
