Question
Chemistry Question on Alcohols, Phenols and Ethers
Boiling point of alcohol is comparatively higher than that of corresponding alkane due to
A
intermolecular hydrogen bonding.
B
intramolecular hydrogen bonding.
C
volatile nature.
D
None of the above
Answer
intermolecular hydrogen bonding.
Explanation
Solution
Because of intermolecular hydrogen bonding in alcohols, they exist as associated molecules. Consequently, a large amount of energy is required to break these bonds and, therefore, their boiling points are higher than that of the corresponding hydrocarbons (hydrogen bonding is absent in hydrocarbons).
