Question

You have been asked to separate N-methylmorpholine, a base, and benzhydroxamic acid (below), which are currently partitioned between dichloromethane and water in a separatory funnel. To what aqueous PH value should you adjust the system such that the two compounds can be separated? Note: pKay denotes the pKa value of a species conjugate acid. Check all that apply. CH 3 N-methylmorpholine pkaH = 8.36 benzhydroxamic acid pKa = 8.88 Any value below 6 Any value below 8.36 Any value between 8.36 and 8.88 Any value above 8.88 Any value above 11

Explanation / Answer

First and last answers were correct . Hence asnwering middle two questions

compound 1 is B , compound 2 is C ,    compound 3 is A

compound 1 is Hydorgen bond donor , compound 2 is neighther ( no attractions , or dispersion force)

compound 3 is hydorgen bond donor and acceptor
