What is the action of litmus on ethanol?

Options

  1. ALitmus is neutral towards ethanol
  2. BEthanol turns blue litmus to red; confirming acidic nature of ethanol
  3. CEthanol turns red litmus to b1ue; confirming basic nature of ethanol
  4. DEthanol decolorizes litmus through bleaching action

Correct answer

A. Litmus is neutral towards ethanol

Step-by-step solution

Litmus is neutral towards ethanol i.e. its colour does not change on treating it with ethanol / Ethyl alcohol ( C ₂ H ₅ OH ) because OH group attached to it does not dissociate as OH - ion which is responsible for change in colour.
