Answer:
CCl4 has greater london dispersion forces, so a higher boiling point
Explanation:
Step 1: Data given
The boiling point of carbon tetrachloride (CCl4) is higher than that of chloroform (CHCl3)
Chloroform (CHCl3) is polar and carbon tetrachloride (CCl4) is nonpolar.
Molar mass of carbon tetrachloride (CCl4) = 153.82 g/mol
Molar mass of chloroform (CHCl3) = 50,49 g/mol
Step 2:
Carbon tetrachloride (CCl4) has is larger than chloroform, this means it has a greater mass per mol( molar mass) than chloroform.
Carbon tetrachloride (CCl4) has more electrons than chloroform.
Since Carbon tetrachloride (CCl4) has more electrons, it's more polarizable.
Since it's more polarizable, it will have greater London dispresion forces.
These London dispersion forces between the CCl4 molecules will raise the boiling point above the boiling point of chloroform.
