Some examples are CH3OH, H2O, and CH3SH. There is always a close relationship between nucleophilicity and basicity. As a rule of thumb, when a compound is a strong base, it is a strong nucleophile, too: typical examples are the OH¯/H₂O or CH₃O¯/CH₃OH pairs, in which the ... hrnce wmf

"WebYes. Sn1 reactions depend on the stability of the cation formed when the Leaving group had left. So, since tertiary carbocations are most stable of the three will undergo Sn1 reaction easily. Sn2 reactions depend on the fastness of the leaving group. The fastness depends on the Leaving group. " - Hcl nucleophile
