NEET 2026, Chemistry Q39: Group 14 Elements: The Carbon Family

NEET2026Chemistry

Identify the incorrect statement from the following:

A
Oxygen exhibits only $- 2$ oxidation state
B
The order of catenation property of Group 14 elements is C $≫$ Si $>$ Ge $\approx$ Sn.
C
Carbon has the ability to form p $π$ –p $π$ multiple bond with itself.
D
ECl $_{3}$ (E = B and Al) is a monomer when E = B and a dimer when E = Al.

Solution

Oxygen shows several oxidation states: $- 2$ (H $_{2}$ O), $- 1$ (H $_{2}$ O $_{2}$ ), $- 1/2$ (KO $_{2}$ ), $0$ (O $_{2}$ ), $+ 1$ (O $_{2}$ F $_{2}$ ) and $+ 2$ (OF $_{2}$ ). Therefore statement (1) is incorrect.
