Hydroxide is a good leaving group for an SN2 reaction.

2-Bromobutane can only undergo an SN1 reaction.
The energy diagram of an SN1 reaction has more than one activation energy barrier.

The iodide anion is a better leaving group than the chloride anion.
In an SN1 reaction, the rate is dependent upon the concentration of the electrophile.
A solvent that has a broad absorption at 3300 cm-1 in the IR spectrum is a good solvent for an SN2 reaction.
Tertiary carbons cannot undergo SN1 reactions because there is no room for a nucleophillic backside attack.

The intermediate produced in an SN2 reaction is a carbocation.
When writing a mechanism for either an SN2 or an SN1 reaction, two-headed arrows are used.
An SN1 reaction on 2-chloro-2-methylpropane will proceed much faster with iodide as the nucleophile as compared to water.
Sodium methoxide is a better nucleophile than methanol for an SN2 reaction.
In an SN2 reaction, the nucleophile attacks the electrophile in the rate determining step.

A good substrate for an SN1 reaction is 1-chloropentane.
Reaction of (R)-1-bromo-1-deuteroethane with sodium hydroxide yields (S)-1-deutero-1-hydroxyethane.

An SN1 reaction can also be referred to as a solvolysis reaction.
