Question

-The reaction of halogens (Group-VII) and alkane (saturated hydrocarbons) in presence of sunlight is an example of
A-carbation
B-halogenation
C-substitution
D-hydrogenation
i want to know why it will be c

Answer 1

Answer:

substitution reaction

Answer 2

The reactivity of various alkane is directly related to their structures. The answer is option C)Substitution.

Explanation:

• Substitution reactions:- A reaction in which a hydrogen atom of a hydrocarbon is replaced by an atom or group of atoms is called a substitution reaction.
• Alkanes, because of having only C-C and C-H sigma bond undergo only substitution reactions. Halogenation reaction is an example of a substitution reaction and follows its mechanism.

Example,

$CH_4 + Cl_2 \xrightarrow{hv or sunlight} CH_3Cl + HCl$

During chlorination of methane, the methane reacts with chlorine to form chloromethane.
