Q 58 Boiling point is least for
1) 0 1 m urea
2) 0 2 m urea
3) 0 1 m NaCl
4) 0 2 m M g C l 2

Dear Student,

Whenever
a non-volatile substance is dissolved in a solvent, the
boiling
point of the
solvent increases The higher the concentration
(molality),
the higher the boiling
point 
NaCl and MgClâ€‹2 is ionic
solid so it will have more boiling point than non ionic solid
therefore 0 1 m urea will have least boiling point
