Question
Arrange the substances in increasing order (lowest to highest)according to their expected boiling points. ----> carbon disulfide, CS2 294 torr ----> ethyl alcohol,C2H5OH 44 torr ----> methyl alcohol, CH3OH 96torr ----> acetone,(CH3)2CO 186torr Please EXPLAIN youranswer. Arrange the substances in increasing order (lowest to highest)according to their expected boiling points. ----> carbon disulfide, CS2 294 torr ----> ethyl alcohol,C2H5OH 44 torr ----> methyl alcohol, CH3OH 96torr ----> acetone,(CH3)2CO 186torr Please EXPLAIN youranswer.
Explanation / Answer
The boiling point would be increases by increasing theintermolecular forces. In the given compounds , CS2 is a on polar compound it has only thelondon dispersion forces. C2H5OH has the hydrogenbonding forces along with the dispersion forces, dipole dipoleforces methanol has the hydrogen bonding forces andlondispersion forces , dipole-dipole forces acetone has the dipole-dipole forces and dipersionforces. Hence the increasing order of boiling point of the givencompound is CS2 < acetone < methanol < ethanol
