Question

Given the equation: ch4 + br2 → ch3br + hbr which type of reaction does this equation represent? addition hydrogenation

Answer 1

Answer: The given reaction is a type of substitution reaction.

Step-by-step explanation:

Addition reaction is defined as the chemical reaction in which more atoms are added to the given compound. No atom is lost during this particular reaction. In organic chemistry, unsaturated hydrocarbons (alkenes and alkynes) shows thsi type of reaction.

`AB+C\rightarrow ABC`

Substitution reaction is defined as the chemical reaction in which one atom replaces the other atom from a compound. In organic chemistry, this reaction is favoured by saturated hydrocarbons (alkanes) only.

`AB+C\rightarrow AC+B`

Hydrogenation reaction is defined as the chemical reaction in which hydrogen atoms are increased in a given compound. This is more favoured by alkenes and alkynes (unsaturated hydrocarbons).

`H_2C=CH_2+H_2\rightarrow CH_3-CH_3`

The given chemical reaction follows:

`CH_4+Br_2\rightarrow CH_3Br+HBr`

In the above reaction, bromine is substituting hydrogen from methane molecule to form methane bromide. So, the above reaction is a substitution reaction.

Answer 2

Answer is: this reaction is substitution.
Substitution reaction or single displacement reaction is a chemical reaction in which one functional group in a chemical compound is replaced by another functional group, in this example one atom of bromine replaced one otom of hydrogen in methane (CH₄).
