In JEE Advanced 2021 (a popular competitive exam in india), a question was asked in Chemistry section about hybridization of atoms. The question is as follows:

The provisional answer is 8. But, i think that they forgot to consider the fact that oxygen in oxime will also participate in resonance. So the answer should be 12.

  • $\begingroup$ It might be tempting to just state the answer since the question is one line only. But because ozonolysis, its reductive workup, and formation of the oximes represent a multi step reaction sequence, it would be helpful for you (and either a grader or a reader of chemistry.se) to see the intermediates up to and including P. In the exam, you still may enter the number, regardless of the number of intermediate steps drawn. Add this here to show your reasoning. $\endgroup$
