Question

Product (Q) is:

(A)

(B)

(C)

(D)

Answer 1

Hint Halogens undergo additional reactions with unsaturated hydrocarbons that give the halogenated product after completion of the reaction. In the presence of methanol halogenated alcohols undergo reaction and form ester as the products.

Complete step by step answer:
- In the question it is asked to identify the product Q in the given chemical reaction.
- The given chemical reaction is as follows.

- The given chemical reaction is a two-step process.
- In the first step the alkene undergoes a reaction with bromine and the chemical reaction is as follows.

- The above reaction is an example of an additional reaction.
- The product formed (P) in the above chemical reaction, reacts with methanol and forms an ester as the product Q and the chemical reaction is as follows.

- The above reaction is an example for elimination reaction and one mole of hydrochloric acid and one moles of hydrogen bromide are going to form as byproducts in the above chemical reaction.
- The product Q contains an ester functional group and a bromine atom is present in the chain at carbon-2.
- Therefore the product Q formed in the given chemical reaction is as follows.

- So, the correct option is B.

Note: Generally halogens undergo halogenation reaction with unsaturated hydrocarbons very easily and form a halide derivative as the product. In this reaction the product contains a saturated hydrocarbon chain in its structure. Esters are organic compounds having a general formula of RCOOR.
