Why does CH3CH2Br have a higher boiling point than CH3CH2Cl, even though CL is more electronegative resulting in a more polar molecule?

Because Br is heavier which makes Ch3Ch2Br heavier and having stronger vander waals forces

due to its greater molar mass, the Br cpd has more electrons which are more polarizable leading to greater London dispersion forces
