Question

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.

Answer 1

Answer:

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
