Question

Which of the following will have the highest boiling point at $1atm$ pressure?

• A. $0.1MNaCl$
• B. $0.1M$ sucrose
• C. $0.1MBaC{l}_2$
• D. $0.1M$ glucose

Answer 1

Answer: (C)

$BaC{l}_2$ Gives maximum ions hence, it shows lowest vapour pressure and highest boiling point
( $\Delta T_b\alpha n;n$ is the number of ions).
