Among the isomeric alkanes of molecular formula C₅H₁₂. Identify the one that on photochemical chlorination yields:

• A) A single monochloride
• B) Three isomeric monochlorides
• C) Four isomeric monochlorides

Isomeric alkanes with the molecular formula C₅H₁₂ can produce different numbers of monochlorides when subjected to photochemical chlorination. Here’s a breakdown of the alkanes and their corresponding monochloride products:

Monochloride Products from C₅H₁₂ Isomers

A) A Single Monochloride

The alkane n-pentane (straight-chain) will yield only one type of monochloride. This is because all hydrogen atoms are equivalent, leading to a single product upon chlorination.

B) Three Isomeric Monochlorides

The branched alkane 2-methylbutane produces three different isomeric monochlorides. The presence of the methyl group creates distinct environments for chlorination, resulting in three unique products.

C) Four Isomeric Monochlorides

The alkane 2,2-dimethylpropane can yield four isomeric monochlorides. The various positions of the chlorine atom on the branched structure lead to multiple distinct chlorinated products.

In summary, the specific alkane determines the number of monochloride isomers formed during chlorination:

• n-pentane: A single monochloride
• 2-methylbutane: Three isomeric monochlorides
• 2,2-dimethylpropane: Four isomeric monochlorides
