QuestionChemistry / states of matter
At a given temperature and pressure, the force of attraction among the molecules will be highest in case of:
- (a) helium
- (b) sugar
- (c) water
- (d) carbon tetrachloride
Answer: (b) sugar
Sugar is a solid; in solids molecules are held by the strongest intermolecular forces (here many H-bonds). Water is liquid; CCl₄ liquid (weak dispersion); helium gas (weakest). Order: sugar > water > CCl₄ > He.
