Why do allylic compounds undergo SN1 and E1 reactions more rapidly than alkyl compounds?

Allylic compounds are more polar, increasing reaction rates.

Allylic compounds have more steric hindrance, facilitating faster reactions.

The resonance stabilization of allylic carbocations makes them more stable, accelerating SN1 and E1 reactions.

Allylic compounds have stronger bonds, promoting faster reactions.
