Question

The major product formed in the following reaction is:

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

The explanation of correct options:

(A)

• Bromination: when a substance undergoes bromination, bromine is added to the compound as a result of the chemical process.
• After bromination, the result will have different characteristics from the starting reactant.
• Only when a double bond is unsymmetrical—that is, when the carbon atoms involved are attached to distinct groups—does a major product and minor product arise, Addition of hydrogen halide to an unsymmetrical alkene the negative part of the group will go to carbon-containing a lesser number of hydrogens.

The explanation for the incorrect options:

(B)

The addition of hydrogen halide to an unsymmetric halide will occur in a way that the negative part will go to carbon-containing a lesser number of hydrogens.

(C)

With the addition of hydrogen halide to an unsymmetrical alkene, the negative part of the group will go to carbon-containing a lesser number of hydrogens.

(D)

The addition of hydrogen halide will not undergo any rearrangement in the parent chain.

Hence, the correct option is (A).
