Q16 / 160 · AP EAMCET 2015 · Chemistry

Identify the correct statement.

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

Solution

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

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