Question

Example(s) of super octet molecule is/are:

• A. $Cl{F}_3$
• B. $PC{l}_5$
• C. $I{F}_7$
• D. All of the above

Answer 1

The correct option is D All of the above

A super octet molecule is the one which has more than 8 electrons in an ultimate shell around the central atom.

A) In $Cl{F}_3$, $Cl$: $\left[Ne\right]3s^{2}3p^5$; $Cl$ has $10$ electrons in ultimate shell and $7e^{-}$ in valence shell.

B) In $PC{l}_5$, $P$: $\left[Ne\right]3s^{2}3p^3$; $P$ has $10$ electrons in ultimate shell and $5e^{-}$ in valence shell.

C) In $I{F}_7$, $I$: $\left[Kr\right]5s^{2}4d^{10}5p^5$; $I$ has $14$ electrons in ultimate shell and $7e^{-}$ in valence shell.
