(a)
To determine:
Methyl alcohol solution in water has a lower boiling point than the NaCl solution
EXPLAINATION:
When 1 mol of methyl alcohol is added to 1 L of water it gets miscible to water to
a considerable extent because of Hydrogen bonds formed by methyl alcohol with
water molecules. While on other hand alcohols are highly volatile too. So by high
volatility action the solution starts boiling at comparitavely lower temperature than
expected.
Whereas when 1 mol NaCl is added the boiling point increases because addition of a solute to pure solvent elevates the boiling point and except that NaCl have a Lower vapour pressure value and it requires more temperature to boil and as a result boiling point increases for NaCl solution.
