If for the sucrose solution elevation in boiling point is `0.1^(@)C`then what will be the boiling point of NaCl solution for same molal concentration

Options

A. `0.1^(@)C`
B. `0.2^(@)C`
C. `0.08^(@)C`
D. `0.01^(@)C`

Answer

B

Explanation

Elevation in a boiling point is a colligative property as it depends upon the number of particles.
`Delta T_(b) ptop n`
For sucrose, `n = 1, Delta T_(b) = 0.1^(@)C`
For NaCl, n = 2, `Delta T_(b)=0.2^(@)C`
