There are two proposed mechanisms for the reaction: CH3CH2Br + OH- → CH3CH2OH + Br Mechanism (1): Step 1: CH3CH2Br → CH3CH2 + + Br Mechanism (2): Step 1: CH3CH2Br + OH- → CH3CH2OH + Br Step 2: CH3CH2 + + OH- → CH3CH2OH a) What is occurring in each mechanism at the molecular level? b) Identify any intermediates in the mechanisms. c) Which step could be the rate-determining step in Mechanism (1)? Explain. d) How might we experimentally determine the correct mechanism?
