Question

Octet rule is applicable to which of the following species?

• A. $Br{F}_5$
• B. $S{F}_6$
• C. $I{F}_7$
• D. $C{O}_2$

Answer 1

The correct option is D $C{O}_2$

a) In $Br{F}_5$, $Br$ has 12 electrons in its valence shell.
b) In $S{F}_6$, $S$ has 12 electrons in its valence shell
c) In $I{F}_7$, $I$ has only 14 electrons in its valence shell.
d) In $C{O}_2$, $C$ has 8 electrons in its valence shell and follows octet rule.
