Answer to Problem 26.33AP
The structure of imitanib in
Explanation of Solution
In imitanib, the aliphatic amine will be protonated than aromatic amine since the basicity of aliphatic amines is more. The aliphatic amine present adjacent to the methyl group will be protonated as it is electron rich due to the
