Question

Which of the following statements is correct regarding hydrogen? (A) Hydrogen shows +1 and -1 oxidation states (B) Hydrogen is never liberated at anode (C) Hydrogen has same ionisation enthalpy as that of alkali metals (D) Hydrogen has same electronegativity as that of halogens

Tardigrade Admin · Accepted Answer

Hydrogen has +1 oxidation state in compounds with more electronegative elements e.g. HF. It has -1 oxidation state in compounds with more electropositive compounds like NaH.

Q. Which of the following statements is correct regarding hydrogen?

Hydrogen shows $+ 1$ and $- 1$ oxidation states

Hydrogen is never liberated at anode

Hydrogen has same ionisation enthalpy as that of alkali metals

Hydrogen has same electronegativity as that of halogens

Hydrogen has $+ 1$ oxidation state in compounds with more electronegative elements e.g. $H F$ . It has $- 1$ oxidation state in compounds with more electropositive compounds like $N a H$ .
