Which of the given statement is not correct

Options

  1. APhenol is more acidic than acetic acid
  2. BEthanol is less acidic than phenol
  3. CEthanol has lower boiling point than ethane
  4. DEthyne is a non-linear molecule

Correct answer

A. Phenol is more acidic than acetic acid

Step-by-step solution

Phenols are much more acidic than alcohols but less so than carboxylic acids or even carbonic acid. This is indicated by the values of ionisation constants. The relative acidity follows the order: K a 1 0 - 5 R C O O H > 1 0 - 7 H 2 C O 3 > 1 0 - 10 C 6 H 5 O H > 1 0 - 14 H O H > 1 0 - 18 R O H
