Question

Alkyl halide cannot be obtained from alkane or alkene by reaction with

Answer 1

Answer: Sodium Chloride (NaCl)

Alkyl halides can be chemically obtained by the following procedures.

(A) Groove's method :

Here, an alcohol reacts with HX in presence of anhydrous zinc chloride.

CH3​CH2​OH+HXanhyd

ZnCl2​​CH3​CH2​Cl+H2​O .

(B) By the combination reaction of an alkane / alkene with thionyl chloride.

CH2​=CH−CH3​SOC​l2​

K​CH2​=CH−CH2​−Cl+SO2​+HCl.

(C) By Borodine-Hunsdiecker reaction.

CH3​COOAg+Br2​/CCl4​→CH3​Br+CO2​+AgBr

Any alkyl halide cannot be prepared by the reaction of any alkene with Sodium Chloride (NaCl).

Eg., When we mix C2​H4 with NaCl, no product is obtained.

C2​H4​+NaCl→No reaction
