Which of the following compounds has the largest intermolecular forces?

  • (a) pentane, C5H11
  • (b) hexane, C6H14
  • (c) heptane, C7H16
  • (d) octane, C8H18

Interpretation Introduction

Interpretation: It should be determined for the largest intermolecular forces among the following compounds. .

Concept introduction:

London dispersion forces:

These forces are often found in the halogen ( F2 and I2 ), the Nobel gases (Ne and Ar) and other non-polar molecule, such as carbon dioxide and methane.

London dispersion forces are first observes in London so it’s named like this.

This is the part of Vander Waals forces, or weak intermolecular attractions.

Explanation of Solution

The major intermolecular force present in Octane C8H18 is Non polar hydrogen or London dispersion forces.

Reasons for incorrect options:

Write all the enthalpy change values in the options except option c.

(a) pentane,C5H14

(b) heptane,C7
