Q. The general molecular formula, which represents the homologous series of alkanols is :
A) CₙH₂ₙO₂
B) CₙH₂ₙO
C) CₙH₂ₙ₊₁O
D) CₙH₂ₙ₊₂O
Explanation
[Solution from source] Alkanols are CₙH₂ₙ₊₁OH, which written as a molecular formula is CₙH₂ₙ₊₂O (e.g. CH₄O for methanol, C₂H₆O for ethanol). CₙH₂ₙO fits aldehydes and ketones, and CₙH₂ₙO₂ fits acids and esters. Answer (4).
