In alcohol, hydrogen bonding is present between oxygen and a hydrogen atom. Sulfur is less electronegative than oxygen and hence, forms a weaker hydrogen bond than in alcohol.
In alcohol, hydrogen bonding is present between oxygen and a hydrogen atom. Sulfur is less electronegative than oxygen and hence, forms a weaker hydrogen bond than in alcohol.
Stronger the hydrogen bonding, higher is the boiling point. Hence, the boiling point of alcohol is more than the corresponding thiol.
