Among the following compound the most volatile is HCl.The volatility of compound id its property to have high vapour pressure at ordinary temperature.
The order is HCl<HBr<HI<HF
HF due to hydrogen bonding is least volatile.As the molecular weight increases the intermolecular force increses due to vander waal force of attraction.Thus HI is liquid and Hcl is a gas.But due to hydrogen bonding in HF it is least volatile
