The molecular formula for the homologous series of alkanols, also known as alcohols, is represented as:

Correct Answer

(D) CₙH₂ₙ₊₂O

Explanation

Alkanols are characterized by having one hydroxyl group (-OH) attached to a carbon chain. The general formula indicates that for every n carbon atoms, there are 2n + 2 hydrogen atoms and one oxygen atom. This formula reflects the structure of alkanols, making option D the right choice.

Key Points

  • Alkanols are a type of alcohol.
  • They contain a hydroxyl group.
  • The formula shows the relationship between carbon, hydrogen, and oxygen atoms.
