Write the formula and the molecular mass of the third homologue of alcohols. State how the boiling point of an alcohol changes as one moves from lower to higher homologues.
Marking-scheme solution
\(\displaystyle \mathrm{C}_{3} \mathrm{H}_{7} \mathrm{OH}\)
\(\displaystyle =3 \times 12+7 \times 1+16 \times 1+1\)
= 60u
Boiling point of alcohols increases from lower to higher homologues
