MCAT Organic Chemistry 2

Subjects : mcat, science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.

26. Amino group placed on the left of a fischer projection is a?






27. 1. it requires an enzyme to linearize and mutarotate 2. it is not a reducing sugar and give negative Benedict's test






28. Separation is due to charge - with negative charge moving toward positive electrode and positive charge moving toward negative electrode






29. 1. it exists in solution in equilibrium with linear form 2. mutarotation occurs readily 3. it is a reducing sugar - and reacts positively w/ Benedict's reagent
