In general boiling point of covalent compounds is affect due to increasing molecular weight and hydrogen bonding. Thus it is obversed that the boiling point of octanol is greater that water while that of methanol is lesser than water. The other properties which are considerably affected due to hydrogen bond formation are acidic nature, melting point, anamalous behaviour of water below `4^(@)C`., It is therefore concluded that hydrogen bonding palys a vutal role in explaning many observable facts.
Q. `K_(a_(2))` of maleic acid is lesser than `K_(a_(2))` of fumaric acid due to:

Options

A. Intramolecular hydrogen bonding in the formed after one proton removal in fumaric acid
B. Intermolecular hydrogen bonding in the ion formed after one proton removal in maleic acid
C. Intramolecular hydrogen bonding in the ion formed after one proton removal in maleic acid
D. Intermolecular hydrogen bonding in the ion formed after one proton removal in fumaric acid

Answer

C
