Arrange the following in the correct order of their boiling points. \(\begin{array}{|l|l|}\hline I & \left(\mathrm{C}_2 \mathrm{H}_5\right)_2 \mathrm{O} \\hline II & \mathrm{CH}_3\left(\mathrm{CH}_2\right)_3 \mathrm{OH} \\hline III & \begin{array}{l}\mathrm{CH}_3 \mathrm{CH}-\mathrm{CH}_2 \mathrm{OH} \\mathrm{CH}_3\end{array} \\hline IV & \mathrm{CH}_3-\left(\mathrm{CH}_2\right)_3-\mathrm{CH}_3 \\hline\end{array}\)

  1. A I \(\gt\) III \(\gt\) II \(\gt\) IV
  2. B II \(\gt\) I \(\gt\) III \(\gt\) IV
  3. C III \(\gt\) II \(\gt\) I \(\gt\) IV
  4. D II \(\gt\) III \(\gt\) IV \(\gt\) I
Verified Solution

Answer & Solution

Correct Answer

(D) II \(\gt\) III \(\gt\) IV \(\gt\) I

Step-by-step Solution

Detailed explanation

II \(\gt\) III \(\gt\) IV \(\gt\) I \(\mathrm{CH}_3\left(\mathrm{CH}_2\right)_3 \mathrm{OH}\) undergo extensive H -Bonding thus having the highest boiling point. is a branched alcohol so its boiling point decreases because its occupy lower surface area. The…
