What is the order of reactivity of halogen and alkyl groups in the dehydrohalogenation of alkyl halides to give alkenes ?

The reactivity of halogens :- The above order in case of halogens is due to the fact that the size of fluorine is small which makes a strong bond with carbon of alkyl group, thus makes it difficult to break. But on the other hand in case of Iodine the bond between Iodine and Carbon

What are the methods of preparation of Haloalkanes and haloarenes ?

Why Alkynes are less reactive than alkenes and alkanes towards electrophilic addition reaction ?

There are two reasons for less reactivity of Alkynes towards electrophillic addition reactions:- Due to greater electronegativity of sp-hybridized carbon atoms of a triple bond than sp2 -hybridized carbon atoms of a double bond, pie-electrons of alkynes are more tightly held by the carbon atoms than pie electrons of alkenes and hence are less easily
