Question

In which of the following compounds does the central atom obey the octet rule?

• A. $Xe{F}_4$
• B. $AlC{l}_3$
• C. $S{F}_6$
• D. $SC{l}_2$

Answer 1

Answer: (A)

$Xe{F}_4$

$12e^{-}$in outermost orbit so it does not obey the octet rule.

$AlC{l}_3$

$6e^{-}$ in outermost orbit so does not obey octet rule.

$S{F}_6$

$12e^{-}$ in outermost orbit so does not obey octet.

$SC{l}_2$

$8e^{-}$ in outermost orbit so it obeys the octet rule.
