Question

"Carboxylic acids can be made by the hydrolysis of nitriles, which in turn can be made from an alkyl halide. Draw the structures of a starting alkyl bromide and the intermediate nitrile that would be used in the synthesis of 3-methylbutanoic acid (also known as isovaleric acid). Do not show free ions."

I answered the first part right but it is saying that the second part is incorrect. On my carbon that is triple bonded to the nitrogen has a negative charge. Sorry for the bad quality picture.
