identify the correct statement

Options

A. Lead forms compounds in +2 oxidation state due to inert pair effect.
B. All halogens show only negative oxidationn state
C. Catenation property increases from boron to oxygen
D. Oxidation state of oxygen is -1 in ozonides

Answer

A

Explanation

Lead forms compounds in + 2 oxidation state due to inert pair effect.
`rarr` All the halogens show an oxidation state of -1. Fluorine being the most electronegative element always shows an oxidation state of -1 while, other, halogens also show positive oxidation states upto a maximum of +7 (i.e. + 1, + 3, + 5 and + 7) due to availability of vacant d-orbitals.
`rarr` Catenation property does not increase from boron to oxygen as carbon shows maximum tendency of catenation.
`rarr` Oxidation state of oxygen is `-(1)/(3)` in ozonides.
