What type of intermolecular force is responsible for the exceptionally high boiling point of water relative to hydrogen sulfide ()?
Answer and explanation
Correct answer: D. Hydrogen bonding
- Step 1: Water molecules possess hydrogen atoms bonded to highly electronegative oxygen atoms.
- Step 2: This establishes strong intermolecular hydrogen bonds between the partially positive H and lone pairs of oxygen on adjacent water molecules, requiring substantial thermal energy to break.
Answer
Hydrogen bonding.
Why not the others: 'London dispersion forces' are weak induced dipole attractions present in all molecules; 'Dipole-induced dipole forces' exist between polar and non-polar species; 'Covalent network bonding' occurs in diamond and quartz.
