A. ethanol
B. ethylene glaycol
C. glycerol
D. methanol
¨ Glycerol has a greater boiling point compared to the other alcohols listed. Glycerol (also known as glycerin or glycerine) has the molecular formula C3H8O3 and contains three hydroxyl (-OH) groups. The presence of multiple -OH groups allows glycerol to form strong hydrogen bonds with other glycerol molecules, resulting in a higher boiling point. Ethanol (C2H5OH) and methanol (CH3OH) have lower boiling points compared to glycerol because they contain only one hydroxyl group and can form weaker hydrogen bonds. Ethylene glycol (C2H6O2) has a boiling point slightly higher than ethanol and methanol because it contains two hydroxyl groups, but still lower than glycerol because it has fewer hydroxyl groups available for hydrogen bonding.
