Identify the correct statement.

Options

  1. ALead forms compounds in +2 oxidation state due to inert pair effect
  2. BAll halogens show only negative oxidation state
  3. CCatenation property increases from boron to oxygen
  4. DOxidation state of oxygen is –1 in ozonides

Correct answer

A. Lead forms compounds in +2 oxidation state due to inert pair effect

Step-by-step solution

Due to inert pair effect, +2 O.S. is more stable than +4 O.S. for lead.
