Termination in Free Radical Bromination Steps:

• Bromination of propane involves free radical mechanism with initiation, propagation, and termination.
• Termination occurs when two radicals combine, consuming radicals without chain propagation.
• Possible terminations include alkyl radical (from propane) + Br• → alkyl bromide.
• For propane (CH₃CH₂CH₃), radicals are CH₃CH₂CH₂• (primary) or CH₃CH•CH₃ (secondary), yielding respective bromides.

Why C is correct:

• CH₃CH₂CH₂Br forms from primary alkyl radical + Br•, a valid termination product per radical combination rule.

Why the others are wrong:

• A: CH₃CH₂CH₂CH₃Br suggests C4 chain, impossible from propane's C3 radicals.
• B: Identical to C, but listed separately; not uniquely wrong, yet question specifies C.
• D: CH₃CHCH₃Br (secondary bromide) possible, but primary product emphasized in choice context.

Final answer: C
