Q7 / 150 · MHT CET 2020 (13 Oct Shift 1) · Chemistry

Which of the following properties of hydrogen is similar to halogen family?

  • Correct answer
    A
    Ionisation enthalpy
  • B
    Formation of unipositive ion
  • C
    Electronic configuration
  • D
    Electron gain enthalpy

Solution

Like halogens, hydrogen exists as a diatomic gas. Like halogens, hydrogen exhibits -1 oxidation state in its compounds with metals. Like halogens, hydrogen is liberated at cathode. The ionisation energy of hydrogen is quite close to halogens.

Hence, the correct answer is option: 'A'.
