Allylic halide with SN1 SN2
Allyl and allylic can react by either SN1 or SN2. It depends on the conditions.
The cations are low enough in energy so SN1 is possible.
But the structures are 1o and 2o, so there is little steric hindrance and SN2 works well also.
At lower T, high concentration of Nucleophile and a good SN2 solvent (polar aprotic), definitely SN2.
At higher T, SN1 will start to compete - if the nucleophile and solvent favor SN1, it can be nearly entirely SN1.
