Question

which of the following will have a higher boiling point? select the correct answer below: o chbr₃ o chcl₃ o they have the same boiling point o there is not enough information to determine this

Explanation:

Step1: Consider intermolecular forces

Both $CHBr_3$ and $CHCl_3$ have dipole - dipole forces and London dispersion forces.

Step2: Analyze London dispersion forces

London dispersion forces are proportional to molar mass. The molar mass of $CHBr_3$ ($M = 12+1+(80\times3)=253\ g/mol$) is greater than that of $CHCl_3$ ($M = 12 + 1+(35.5\times3)=119.5\ g/mol$). Larger molar - mass leads to stronger London dispersion forces.

Step3: Determine boiling point

Stronger intermolecular forces result in a higher boiling point. Since $CHBr_3$ has stronger London dispersion forces, it has a higher boiling point.

Answer:

A. $CHBr_3$
