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. `0.08^(@)C`
C. `0.2^(@)C`
D. `0.01^(@)C`

Answer

C

Explanation

Elevation in aboiling point is a colligative property as it depends upon the number of particles.
`DeltaT_(b)propn`
for sucrose,n=`1,DeltaT_(b)=0.1^(@)C`
for NaCl,n=`2,DeltaT_(b)=0.2^(@)C`
