Question

Why is the boiling point of alcohol 351K ?
Why is the boiling point of benzene 353K ?

Answer 1

Benzene and methanol cannot be separated by simple distillation as the difference in their boiling points is less than 25 K. Simple distillation is used when the difference in the boiling points is in the range 25-50 K.When the difference is less than 25 K, fractional distillation is used.Hence, the assertion is incorrect and the reason is correct.
