   Q1. Why is the boiling point of ethanol higher compared to methanol?

   • A) Due to the presence of a hydroxyl group
   • B) Due to the presence of a methyl group
   • C) Due to the difference in molecular size
   • D) Due to the difference in molecular weight

   Answer: Due to the difference in molecular size

   Explanation: Ethanol has a larger molecular size and stronger intermolecular forces due to hydrogen bonding, resulting in a higher boiling point.
