Explain the polarity of both CH3CH2Br and CBr3CBr3.
Both molecules have a C-Br bond, which will be polar due to their difference in electronegativities (bromine is more electronegative than carbon). In CBr3CBr3 the dipoles cancel so the overall molecule is non-polar. However, in CH3CH2Br one side will be slightly more negative (bromine side).
