Question

Carbon is present in highest oxidation number in ______.

विकल्प

• CO

• CaC₂

• \[\ce{C2O^{2-}_4}\]

• \[\ce{CO^{2-}_3}\]

Answer 1

Carbon is present in highest oxidation number in \[\underline{\ce{CO^{2-}_3}}\].

Explanation:

+2	-1	+3	+4
↑	↑	↑	↑
CO	CaC2	\[\ce{C2O^{2-}_4}\]	\[\ce{CO^{2-}_3}\]

Here, highest oxidation number = + 4 in \[\ce{CO^{2-}_3}\]
