True or false? 2-bromo-2-methylpropane undergoes SN1 rather than SN2 because the nucleophile experiences steric hindrance, and a stable carbocation can be formed. When hydroxide ion reacts with 1-chloropropane the main product is 1-propanol.
Q4 Which statement below about Sn1 reactions is incorrect? (A) SN1 reactions are stepwise and have intermediates. (B) The slow step in a SN1 reaction is formation of the carbocation intermediate. (C) SN1 reactions have first order kinetics which means only the alkyl halide is involved in the rate limiting step. (D) The products of a SN1 reaction will be a pair of enantiomers. (E) An aprotic solvent is best for Sn1 reactions as they tend to help stabilize carbocation intermediates.
