CHXI04:CHEMICAL BONDING AND MOLECULAR STRUCTURE

313611 Water is a liquid while hydrogen sulphide is a gas because

1 Water has higher molecular weight
2 Hydrogen sulphide is a weak acid
3 Sulphur has high electronegativity than oxygen
4 Water molecules associate through hydrogen bonding

313612 Hydrogen bonds are formed in many compounds e.g., \({{\rm{H}}_{\rm{2}}}{\rm{O,}}\,\,{\rm{HF,}}\,\,{\rm{N}}{{\rm{H}}_{\rm{3}}}{\rm{.}}\) The boiling point of such compounds depends to a large extent on the strength of hydrogen bond and the number of hydrogen bonds. The correct decreasing order of the boiling points of above compounds is:

1 \({\rm{HF > }}{{\rm{H}}_{\rm{2}}}{\rm{O > N}}{{\rm{H}}_{\rm{3}}}\)
2 \({{\rm{H}}_{\rm{2}}}{\rm{O > HF > N}}{{\rm{H}}_{\rm{3}}}\)
3 \({\rm{N}}{{\rm{H}}_{\rm{3}}}{\rm{ > HF > }}{{\rm{H}}_{\rm{2}}}{\rm{O}}\)
4 \({\rm{N}}{{\rm{H}}_{\rm{3}}}{\rm{ > }}{{\rm{H}}_{\rm{2}}}{\rm{O > HF}}\)
