Question
The cyclopropenyl cation ($C_3H_3^+$) is highly stable for a small strained ring. What is its exact integer value for '$n$' in Huckel's $(4n+2)$ rule?
Answer: A
💡 Solution & Explanation
The planar cyclopropenyl cation contains 1 double bond ($2\pi$ electrons) and an empty p-orbital. Setting $4n + 2 = 2 \implies 4n = 0 \implies n = 0$. It is a perfectly valid aromatic system.
