\n\n\n\nCorrect Ranking by Boiling Point:<\/h3>\n\n\n\n
Intermediate boiling point: CH\u2083CH\u2082CH\u2082CH\u2082CH\u2082CH\u2082OH (hexanol)<\/strong>
Highest boiling point: CH\u2083CH\u2082CH\u2082CH\u2082COOH (pentanoic acid)<\/strong><\/p>\n\n\n\n
\n\n\n\nExplanation:<\/h3>\n\n\n\n
\n
\n\n\n\n\n
This compound has a triple bond<\/strong> and is nonpolar. The primary intermolecular force is London dispersion<\/strong>. It lacks groups like -OH or -COOH, so it cannot hydrogen bond. Therefore, it has the lowest boiling point<\/strong>.<\/li>\n<\/ol>\n\n\n\n
\n\n\n\n\n
Hexanol has a hydroxyl group (-OH)<\/strong>, which allows for hydrogen bonding<\/strong>, increasing its boiling point. However, alcohols generally have lower boiling points than carboxylic acids because they form fewer hydrogen bonds per molecule.<\/li>\n<\/ol>\n\n\n\n
\n\n\n\n\n
Carboxylic acids have both a hydroxyl and a carbonyl group<\/strong>, allowing them to form strong dimeric hydrogen bonds<\/strong>. This makes their boiling points higher than alcohols<\/strong> and far higher than hydrocarbons or alkynes.<\/li>\n<\/ol>\n\n\n\n
\n\n\n\nConclusion:<\/h3>\n\n\n\n
CH\u2083CH\u2082C\u2261CHCH\u2082CH\u2083 < CH\u2083CH\u2082CH\u2082CH\u2082CH\u2082CH\u2082OH < CH\u2083CH\u2082CH\u2082CH\u2082COOH<\/strong>.<\/p>\n\n\n\n![\"\"](\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-156.jpeg\")
