Question:
In the given structure, number of \( sp \) and \( sp^2 \) hybridized carbon atoms present respectively are: 
In the given structure, number of \( sp \) and \( sp^2 \) hybridized carbon atoms present respectively are:
Show Hint
Carbon atoms involved in triple bonds are \( sp \)-hybridized, while those involved in double bonds (or with a lone pair) are \( sp^2 \)-hybridized.

The Correct Option is A
Solution and Explanation
- The structure contains \( sp \) and \( sp^2 \) hybridized carbon atoms.
- The carbon atoms in triple bonds (i.e., the C≡N bond) are \( sp \)-hybridized.
- The carbon atoms in the C=C double bonds and in the C=O group are \( sp^2 \)-hybridized.
- Thus, the number of \( sp \)-hybridized atoms is 3 and the number of \( sp^2 \)-hybridized atoms is 5.
Final Answer: Option (1).
