Answer 1

Acc. To me,

1.Halogenation

In this rxn halogen add with alkene in presence of sunlight (hv) to give haloalkane

Rxn:

C2H4+Cl2---->C2H4Cl2

Alkene+chlorine=haloalkane

2.Freidal Craft

In this rxn methyl grp(always alkyl grp) add with benzene (in presence of AlCl3)at Ortho or para position to form toluence or other comp.

Rxn:

Benzene(C6H6)+CH3Cl--->(C6H5CH3)toluene

3.Wurtz

In this rxn Two haloalkane react with Sodium in presence of dry ether to give alkane and Salt.

Rxn:

2CH3CL(chloromethane)+2Na-->CH3CH3(Ethane)+2NaCl

I hope it help
