Step 1: Understanding Neohhexyl chloride.
Neohhexyl chloride is a compound with a branching structure where a chlorine atom is attached to a carbon atom in the structure. In this case, the correct structure is (CH\(_3\))\(_3\)C-CH\(_2\)-CH\(_2\)-Cl.
Step 2: Analyzing the options.
(A) (CH\(_3\))\(_3\)C-CH\(_2\)-CH\(_2\)-Cl: Correct — This is the structure of neohhexyl chloride.
(B) CH\(_3\)-(CH\(_2\))\(_4\)-CH\(_2\)-Cl: This structure does not match neohhexyl chloride.
(C) (CH\(_3\))\(_2\)CH-CH\(_2\)-CH\(_2\)-Cl: This structure does not represent neohhexyl chloride.
(D) (CH\(_3\))\(_3\)C-CH\(_3\)-Cl: This is an incorrect structure for neohhexyl chloride.
Step 3: Conclusion.
The correct answer is (A) (CH\(_3\))\(_3\)C-CH\(_2\)-CH\(_2\)-Cl.
