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

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
