Question

reaction of ethyl bromide with alcoholic silver cyanide

Answer 1

C2H5Br+AgNO3--------C2H5NO3+ AgBr
AgNO3 is covalent in nature so product is nitro compound.

Answer 2

Answer: The product formed will be ethaneisonitrile.

Explanation:

When ethyl bromide (haloalkane) reacts with alcoholic solution of silver cyanide, it results in the formation of ethaneisonitrile (alkaneisonitrile) via $S_N1$ mechanism. The attack of nucleophile in this case occurs through nitrogen atom.

Hence, the product formed will be ethaneisonitrile and the equation for the above reaction is given below.
