Question

why do haloalkanes and haloarenes have high MP and BP than hyrocarbon​

Answer 1

$\implies$The melting points and boiling points of haloalkanes are higher than those of corresponding hydrocarbons due to higher molecular mass of haloalkanes.Because p-isomers are more symmetrical and hence their molecules pack closely in the crystal lattice. This leads to stronger molecular forces of attraction.
