The general molecular formula, which represents the homologous series of alkanols is:

• Correct answer
  A

  $\mathrm{C}_n \mathrm{H}_{2 n+2} \mathrm{O}$
• B

  $\mathrm{C}_n \mathrm{H}_{2 n} \mathrm{O}_2$
• C

  $\mathrm{C}_n \mathrm{H}_{2 n} \mathrm{O}$
• D

  $\mathrm{C}_n \mathrm{H}_{2 n+1} \mathrm{O}$

Solution

Alkanols are the derivatives of alkanes which are derived by the replacement of the $-\mathrm{H}$ of alkanes with the $-\mathrm{OH}$ (hydroxyl) group.

Hence, the correct answer is option: 'A'.
