Let's look at the laundry list you've collected in a better format,
Every substrate you listed could generally undergoes a bimolecular nucleophilic substitution reaction, except
Moreover, the primary alkyl halides would undergo SN2, the secondary alkyl halides could undergo either SN1 or SN2 (esp. dependent on the other conditions), and the tertiary alkyl halide

The factors that determine whether a compound undergoes SN1, SN2, or both mechanisms include:
- Substrate structure: SN1 reactions typically occur with tertiary substrates due to the stability of the carbocation intermediate, while SN2 reactions favor primary substrates where steric hindrance is minimal.
- Nucleophile strength: SN2 reactions are favored by strong nucleophiles, whereas weak nucleophiles tend to favor SN1 reactions.
- Leaving group ability: Compounds with good leaving groups favor both SN1 and SN2 reactions.
- Solvent effects: Polar protic solvents favor SN1 reactions, while polar aprotic solvents favor SN2 reactions.
- Reaction conditions: Temperature and concentration can influence the mechanism preference, with higher temperatures and lower concentrations favoring SN1 and vice versa for SN2.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
