Q. The following carbocation is stabilized by the interaction of the empty p orbital with C₆H₅–C⁺H–CH₃
A) empty σ* and empty π* orbitals
B) filled σ and filled π orbitals
C) empty σ and empty π* orbitals
D) empty σ* and filled π orbitals
Explanation
[Solution from source] The 1-phenylethyl cation is stabilised by resonance (overlap of the empty p orbital with the filled π orbitals of the ring) and by hyperconjugation (overlap with filled C–H σ orbitals). An empty orbital is stabilised only by donation from filled orbitals. Answer (2).
