There are three different substances, Argon, Hydrochloric acid and Hydroiodicacid. The correct sequence in which the boiling point increases is

Correct answer: A. Ar < HCI < HI

  • A. Ar < HCI < HI
  • B. HI > HCI > Ar
  • C. HCI < HI < Ar
  • D. HI > Ar > HCI

Explanation

Argon (Ar) is a noble gas and exists as individual atoms with weak van der Waals forces between them. It has the lowest boiling point among the given substances.Hydrochloric acid (HCl) is a polar covalent molecule with dipole-dipole forces. It has a higher boiling point compared to Argon.Hydroiodic acid (HI) is a polar covalent molecule with stronger dipole-dipole forces than HCl. It has the highest boiling point among the given substances.

About Atomic Structure

Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
