Question

1. For the reaction below, draw the structure of the resulting reactive intermediate A Now, consider the reaction of intermediate A with each of the halides/pseudohalides below, which isfollowed by aqueous acid work-up: (i) Draw the structure of the expected product(s) immediately below thecorresponding given halide/pseudohalide, and (ii) Indicate below the product(s) what reaction type (e.g., E1)is involved in each of these reactions.
