Question

Addition of bromine to $1,3$-butadiene gives
A) $1,{\text{ }}2$ addition products
B) $1,{\text{ }}4$ addition products
C) Both $1,{\text{ }}2$ and $1,{\text{ }}4$ addition products
D) No reaction

Answer 1

Organic chemistry, hydrocarbon is an important topic. Hydrocarbon is majorly classified into three groups. There are alkane, alkene and alkyne. The alkane means carbon-carbon single bond. The alkene having a carbon-carbon double bond. The alkyne defined carbon-carbon having a triple bond in the molecule. The general formula of an alkane is ${{\text{C}}_{\text{n}}}{{\text{H}}_{{\text{2n + 2}}}}$. The general formula of an alkene is ${{\text{C}}_{\text{n}}}{{\text{H}}_{{\text{2n}}}}$. The general chemical formula of the alkyne is ${{\text{C}}_{\text{n}}}{{\text{H}}_{{\text{2n - 2}}}}$.

Complete answer:
The given statement is below,
Addition of bromine to $1,3$-butadiene
The molecular formula of $1,3$-butadiene is${C_4}{H_6}$.
The structural formula of $1,3$-butadiene is
$C{H_2} = CH - CH = C{H_2}$
The bromination of $1,3$-butadiene is possible to give two positional isomers. The positional isomers are formed in addition of bromine to $1,3$-butadiene is $1,{\text{ }}2$-dibromobutene and $1,{\text{ }}4$-dibromobutene. Addition of bromine to $1,3$-butadiene is kind of addition reaction.
The chemical reaction for the addition of bromine to $1,3$-butadiene is given below,
According to the above discussion, we conclude addition of bromine to $1,3$-butadiene gives both $1,{\text{ }}2$ and $1,{\text{ }}4$ addition products.

Hence, option C is the correct answer for the addition of bromine to $1,3$-butadiene.

Note:
Alkyl halides are classified into three types. There are primary alkyl halide, secondary alkyl halide, and tertiary alkyl halide. The expansion of IUPAC is the International Union of Pure and Applied Chemistry. It is a World Wide organization for the nomenclature of the new elements in the periodic table and chemical molecules. The IUPAC having certain rules and regulations for naming the organic compound. In that method only we named the organic molecules at the World level. The naming of any organic molecule depends on the parent saturated hydrocarbon.
