For the following SN2 reaction, draw the organic and inorganic products of the reaction, and identify the nucleophile, substrate, and leaving group. Select the statement that properly identifies the nucleophile, substrate, and leaving group. Br- is the substrate, CH3C≡C:- is the nucleophile, and CH3Br- is the leaving group. CH3Br- is the substrate, CH3C≡C:- is the nucleophile, and Br- is the leaving group CH3C≡C:- is the substrate, CH3Br- is the nucleophile, and Br- is the leaving group
