Question & Answer: Indicate whether the specified alkyl halides will form primarily substitution products, only…..

A) substitution product

1-bromopropane with methanol forms substitution product under S_N1 condition. This is because1-bromopropane is primary alkyl halide and methanol is very weak base but moderate nucleophile. Thus it forms substitution product under S_N1 condition.

B) Both substitution and elimination product

1-bromopropane with sodium methoxide forms both substitution and elimination product under S_N2/E₂conditions. This is because1-bromopropane is primary alkyl halide and sodium methoxide is strong base but moderate nucleophile. Thus it forms both substitution and elimination product under S_N2/E₂conditions.

E) substitution product

2-bromopropane with methanol forms substitution product under S_N1 condition. This is because2-bromopropane is secondary alkyl halide and methanol is very weak base but moderate nucleophile. Thus it forms substitution product under S_N1 condition.

F) Both substitution and elimination product

2-bromopropane with sodium methoxide forms both substitution and elimination product under S_N2/E₂conditions. This is because 2-bromopropane is secondary alkyl halide and sodium methoxide is strong base but moderate nucleophile. Thus it forms both substitution and elimination product under S_N2/E₂conditions.

G) substitution product

Because methanol is very weak base

H) Elimination product

Sodium methoxide is strong base. So it forms elimination product with 2-bromo-2-methylpropane.
