Question

. Which of the following compound
has highest boiling point ?
a. n-pentane
b. iso-butane
c. butane
d. neopentane​

Answer 1

Answer:

The boiling point of n- pentane is 36.1 degrees celsius. The boiling point temperature of butane is -0.4°C. The boiling point of neopentane is 9.5 degrees celsius. The boiling point of isobutane is -11.7 degrees celsius. So n-pentane has the highest boiling point.

Answer 2

n-pentane has the highest boiling point. (Option A)

• Because it may develop a rodlike structure in which neighboring molecules can pack closely together, n-pentane melts faster than others.
• The lengthy n-pentane molecules fit together quite well and have the strongest intermolecular attraction.
• N-pentane has a boiling point of 36°C.
• The surface area of a simple long chain compound will be greater than that of a branched-chain complex.
• As a result, branched-chain compounds require less temperature than simple long-chain molecules.
• Iso-pentane has a boiling point of 28°C while neo-pentane has a boiling temperature of 10°C.
• Isobutane has a boiling point of -11.7°C.
• Branched-chain molecules include iso-pentane, neo-pentane, and isobutane.
