Which of the following set of compounds does not follow octet rule?}
Show Hint
Common expanded octet examples:
\[
PF_5,\ SF_6,\ PCl_5,\ H_2SO_4
\]
These usually involve elements from the third period or beyond.

- \(SCl_2, PF_5\) and \(SF_6\)
- \(CH_4, PF_5\) and \(SF_6\)
- \(PF_5, H_2SO_4\) and \(SF_6\)
- \(PF_5, H_2SO_4\) and \(SCl_2\)
- \(SCl_2, H_2SO_4\) and \(SF_6\)
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Compounds that do not follow octet rule generally show expanded octet.
Check each important compound:
Hence, the correct answer is: \[ \boxed{(C)} \]
- \(PF_5\): phosphorus has 10 electrons around it.
- \(SF_6\): sulfur has 12 electrons around it.
- \(H_2SO_4\): sulfur shows expanded valency in the usual Lewis description.
Hence, the correct answer is: \[ \boxed{(C)} \]
