Question

Select the correct increasing order of their boiling point.

• A. $n$-pentane, ethoxyethane, butan-$1$-ol
• B. ethoxyethane, $n$-pentane, butan- $1- ol$
• C. butan-$1$-ol, $n$-pentane, ethoxyethane
• D. ethoxyethane, butan-$1$-ol, $n$-pentane

Answer 1

Answer: (B)

The weak polarity of ethers do not appreciably affect their boiling points which are comparable to those of the alkanes of comparable molecular masses but are much lower than the boiling point of alcohols.

	$n$ -pentane	Ethoxyethane	Butan -$1$-ol
Boling point	$309.1$	$307.6$	$390$
