(A) Predict whether the following reactions will take place, and suggest the likely mechanism:

(a) CH₃CC⁻ + CH₃Br →

(b) Cl⁻ + CH₃CH₂CN →

(c) CH₃NH₂ + (CH₃)₃CCl →

(B) From the following information, state whether the reaction proceeds by an S_N1 or S_N2 mechanism. Then, write a detailed mechanism for the reaction.

(a) The following reaction is carried out in acetone (propanone):

(b) A sample that contains only one enantiomer (either R or S) of an optically active compound is said to be optically pure. An optically pure sample of 2-iodobutane is dissolved in methanol. The resultant solution of 2-methoxybutane is optically inactive.
