Question 38

Identify structure of 2, 3-dibromo-1-phenylpentane.

The parent chain is pentane, which contains a continuous chain of five carbon atoms.

A phenyl group is attached to carbon 1 of the pentane chain. Therefore, numbering must begin from the end nearest the phenyl group.

The name also specifies the presence of two bromine substituents at carbon 2 and carbon 3.

In Option A, the bromine atoms are present at carbon 1 and carbon 3. Therefore, it represents $$1,3\text{-dibromo-1-phenylpentane}$$.

In Option B, the bromine atoms are present at carbon 3 and carbon 4. Therefore, it represents $$3,4\text{-dibromo-1-phenylpentane}$$.

In Option D, the bromine atoms are present at carbon 1 and carbon 2. Therefore, it represents $$1,2\text{-dibromo-1-phenylpentane}$$.

In Option C, the phenyl group is attached to carbon 1, while the bromine atoms are attached to carbon 2 and carbon 3. The remaining two carbons complete the pentane chain.

Thus, Option C correctly represents

$$2,3\text{-dibromo-1-phenylpentane}$$

Hence, the correct answer is Option C.
