4-chloro-3,4-dimethylnonan-1-amine On a page titled Incorrect Separation Scheme print the incorrect separation schemeprovided for your molecule on Blackboard. The top of the separation scheme shows whatother compound is mixed with your molecule. Assume for the purposes of this assignmentthat both compounds are solid at room temperature. Also assume that both compounds aresoluble in ether, except ionic compounds. The goal of the separation is the isolate each ofthe two compounds from the mixture.o Below the incorrect separation scheme write a discussion of this incorrect schemeidentifying all of the mistakes in the separation scheme. Keep in mind that therewill be more than one mistake in the scheme.o For each mistake, give a detailed, scientific explanation of why it is incorrect.
