Alkyl halides undergo substitution reactions with nucleophiles. Strong nucleophiles favor the mechanism over the mechanism. An SN1 mechanism forms a as a reactive intermediate and the mechanism has . Protic solvents favor mechanism and aprotic solvents favor the . reactions proceed with racemization at a single stereogenic center. Increasing alkyl substitution favors an mechanism while decreasing alkyl substitution favors an mechanism. A is a positively charged carbon atom.

Substitution; SN2, SN1; carbonation, two steps; SN1,SN2

Explanation:

Alkyl halides undergo substitution reactions with nucleophiles. Strong nucleophiles favor the SN2_ mechanism over the _SN1_ mechanism. An SN1 mechanism forms a carbonation as a reactive intermediate and the mechanism has two steps. Protic solvents favor SN1 mechanism and aprotic solvents favor the SN2 . SN1 reactions proceed with racemization at a single stereogenic center. Increasing alkyl substitution favors an SN1 mechanism while decreasing alkyl substitution favors an SN2 mechanism. A Carbonation is a positively charged carbon atom
