Is sch3 a good nucleophile
Witryna• May overlap with strong nucleophile list (causing mixtures of both substitutions and eliminations to be produced) • Halides and the azide anion are nucleophilic but not basic – only strong nucleophiles that are not also strong bases. Examples: NaOCH3 (any NaOR), LiCH3 (any RLi), NaOH or KOH, NaCN or KCN, NaCCR (acetylide anion), WitrynaStrong nucleophiles…this is why molecules react. The nucleophilic site of the nucleophile is the region of a molecule that is reactive and has the electron density. Strong nucleophiles are VERY important throughout organic chemistry, but will be … Radical reactions: a quick overview first. A radical reaction is a reaction which … Reactions.

A nucleophile is a species that is strongly attracted to a region of positive charge on a carbon atom in another molecule. In NH₃, N is more electronegative than H, so the N atom has a partial negative (δ⁻) charge. It also has a lone pair of electrons.
