a. 3-ethylpentane<\/strong>

Explanation<\/h3>\n\n\n\n

A condensed structural formula<\/strong> provides a streamlined way of writing organic molecules by grouping atoms together while still showing how they are connected. It is especially useful for representing complex branched alkanes in a compact format.<\/p>\n\n\n\n

For 3-ethylpentane<\/strong>, the parent chain is pentane (five carbon atoms), and an ethyl group (CH\u2082CH\u2083) is attached to the third carbon. The chain reads CH\u2083CH\u2082CH(CH\u2082CH\u2083)CH\u2082CH\u2083.<\/p>\n\n\n\n

In 3-ethyl-2-methylpentane<\/strong>, the parent is again a five-carbon pentane chain. A methyl group is on the second carbon, and an ethyl group is on the third carbon. The central backbone is adjusted accordingly to CH\u2083CH(CH\u2083)CH(CH\u2082CH\u2083)CH\u2082CH\u2083.<\/p>\n\n\n\n

4-ethyl-2,2-dimethyloctane<\/strong> has an eight-carbon chain as the parent. Two methyl groups are attached to the second carbon, and one ethyl group is attached to the fourth carbon. Its structure is more branched, requiring careful placement of substituents.<\/p>\n\n\n\n

2-bromopropane<\/strong> is a simple three-carbon propane chain with a bromine atom attached to the second carbon, written as CH\u2083CHBrCH\u2083.<\/p>\n\n\n\n

For 2,3-dichloro-2-methylbutane<\/strong>, the parent chain is butane. A methyl group is attached to the second carbon along with a chlorine, and another chlorine is on the third carbon. This highly substituted molecule is written with nested parentheses to show the branches.<\/p>\n\n\n\n

Each condensed structure reflects carbon bonding rules and helps in predicting physical and chemical behavior.<\/p>\n\n\n\n
