Question

which is more reactive haloalkanes or haloarens ?​

Answer 1

Haloalkenes are more reactive.

Answer 2

Answer:

In haloarenes there is double bond character b/w carbon and halogen due to resonance effect which makes him less reactive. In benzene carbon being sp2 hybridised which is smaller in size than sp3 present in haloalkanes . So C-Cl bond in aryl halides is shorter and stronger.
