Options
- Asp and sp^2
- Bsp^3 and sp
- Csp^2 and sp
- Dsp^2 and sp^3
Correct answer
C. sp^2 and sp
Step-by-step solution
According to IUPAC nomenclature rules, the principal functional group determines the numbering of the carbon chain. The ketone group ( >C=O ) has a higher priority than the alkyne group ( -C C- ). Numbering the chain to give the ketone the lowest possible locant, we start from left to right: C₁ : CH ₃ C₂ : C (= O ) C₃ : CH ₂ C₄ : C C₅ : CH The C₂ atom is bonded to three atoms (one oxygen and two carbons) with no lone pairs, forming 3 bonds and 1 bond. Therefore, its hybridization is sp^2 . The C₄ atom is bonded to
