Which of the following is a false statement?

Options

  1. AMethoxymethane has higher boiling point than ethanol.
  2. BAlcohols are more soluble is water than hydracarbons of comparable molecular mass.
  3. Cortho-and para-nitrophenols are more acidic than phenols.
  4. DPhenol is more acidic than alcohol.

Correct answer

A. Methoxymethane has higher boiling point than ethanol.

Step-by-step solution

Ethanol ( C₂H₅OH ) exhibits intermolecular hydrogen bonding due to the presence of the polar -OH group, which leads to a significantly higher boiling point compared to methoxymethane ( CH₃OCH₃ ), which is an ether and lacks such hydrogen bonding. Therefore, the statement that methoxymethane has a higher boiling point than ethanol is false. Alcohols are capable of forming hydrogen bonds with water molecules, making them more soluble in water than hydrocarbons of comparable molecular mass, which are non-polar. This s
