What is the difference between haloalkane and haloarene?
A haloalkane has halogen on an sp³ carbon and readily undergoes substitution; a haloarene has halogen on an aromatic ring where resonance and the sp² C–X bond make substitution much harder.
A haloalkane has halogen on an sp³ carbon and readily undergoes substitution; a haloarene has halogen on an aromatic ring where resonance and the sp² C–X bond make substitution much harder. A reliable way to keep them apart is to focus on what each one is defined by, not just the similar-sounding words.
