Current Question (ID: 8648)

Question:
$\text{The correct statement among the following regarding hydrogen is-}$
Options:
  • 1. $\text{It can form a bond in +1 as well as -1 oxidation state}$
  • 2. $\text{It is always collected at the cathode}$
  • 3. $\text{It has a very low ionization potential}$
  • 4. $\text{It has the same electronegativity as halogens}$
Solution:
$\text{Hint: Hydrogen can form both Ionic or saline or salt-like hydrides and Covalent hydride.}$ $\text{Hydrogen forms bonds in +1 and -1 oxidation states. In ionic hydride like NaH, the hydrogen oxidation state is -1. In covalent hydride like } \text{H}_2\text{O}\text{, the hydrogen oxidation state is +1.}$ $\text{Hydrogen is not always collected at the cathode.}$ $\text{It has a very high ionization potential.}$ $\text{The hydrogen atom is less electronegativity than halogen.}$
