The halide shown is treated with the reagent named in each option, and the structure drawn is claimed to be the main product. Select all options in which the pairing is correct (textbook convention).

AStructure A, using alcoholic $KCN$
BStructure B, using alcoholic $KCN$
CStructure C, using $AgNO X_{2}$
DStructure D, using $AgNO X_{2}$

Answer: A, C

Alcoholic KCN is ionic and attacks through carbon, so the product is the nitrile (A is correct; B pairs KCN with the isocyanide, which is the AgCN product). AgNO2 gives the nitro compound through N (C is correct), whereas the nitrite ester drawn in D is the KNO2 product.
