Are there any rules regarding what conditions to use for different reactions? I understand why you'd use different reducing agents (e.g. LiAlH4 over H2/Ni), but I don't know why you would use hot ethanolic conditions or warm aqueous conditions

Anybody know?

for the same reagents (a nucleophile and a haloaklane):
Nucleophilic Substitution = Warm, aqueous
Elimination = Hot, ethanolic
