Ethanoic acid (CH3COOH) has a much lower vapor pressure than ethanol (CH3CH2OH). What is the most reasonable explanation? (A) The polarizability of two oxygen atoms increases the London forces of attraction in ethanoic acid compared with ethanol. (B) Hydrogen bonding in ethanoic acid is the strongest attractive force and is mainly responsible for the observed data. (C) Both ethanol and ethanoic acid have an – OH, so the difference is the dipole of the second oxygen that increases the attractive forces. (D) Ethanol has an - OH group and can hydrogen bond; therefore, the London forces must cause the effect.arrow_forward
