How many electrons are present in the nonbonding π molecular orbital of the allyl cation?
A) 0
B) 1
C) 2
D) 3
E) 4
Nonbonding
Pertaining to electrons in an atom or molecule that are not shared with other atoms and do not participate in bonding.
Π Molecular Orbital
A type of molecular orbital formed by the sideways overlap of atomic orbitals, crucial in understanding the bonding in conjugated systems.
Allyl Cation
A positively charged ion with a structure characterized by a carbon atom connected to three other carbon atoms via a sigma bond and two pi bonds, forming a resonance-stabilized intermediate in organic reactions.
- Clarify and describe the contribution of orbitals to organic reactions, emphasizing the roles played by the Highest Occupied Molecular Orbital (HOMO) and Lowest Unoccupied Molecular Orbital (LUMO).

Final Answer :
A
Explanation :
The allyl cation has a structure where the central carbon atom is sp2 hybridized and positively charged, leaving two π electrons distributed over the three carbon atoms. These electrons are in bonding π molecular orbitals, not nonbonding. Therefore, there are 0 electrons in the nonbonding π molecular orbital.
