Haloalkanes and Arenes

Which of the statements are correct about the reactivities of alkene, alkynes, and arenes?

Haloalkanes undergo nucleophilic substitution whereas haloarenes undergo electrophilic substitution. Explain

Why are haloarenes more stable than haloalkanes andundergo electrophilic substitution at ortho and para positions?

Haloarenes are less reactive than haloalkanes and haloalkenes. Explain.

Haloalkanes contain halogen atom(s) attached to the sp^(3) hybridised carbon atom of an alkyl group. Identify haloalkane from the following compounds.

Statement-I: Chloropropane has higher boiling point than chloroethane. Because Statement-II: Haloalkanes are polar molecules.

A haloalkane can be reduced to an alkane with the help of HI in presence of red phosphorus. Red phosphorus

Answer the following: (i) Haloalkanes easily dissolve in organic solvents, why? (ii) What is known as a racemic mixture ? Give an example. (iii) Of the two bromoderivatives, C_6H_5CH (CH_3) Br and C_6H_5CH (C_6H_5)Br , which one is more reactive in S_(n^1) substitution reaction and why?

Which of the following haloalkanes is most reactive?
