300

what category (good, moderate, poor, extremely poor) do the following leaving groups belong in?

NH2-

H-

R-

extremely poor 

400

Categorize the following as strong/weak bases and good/poor nucleophiles

HSO4-

RNH2

ROH

weak bases and bad nucleophiles 

500

A primary substrate reacts with NaOCH

                                           CH3OH, 30 C 

will this favour substitution or elimination pathway?

1% elimination 99% substitution 

why? low heat, good nucleophile, and is a methyl (no other carbon to form double bond with).
