MCAT Organic Chemistry

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.
1. Nonsuperimposable mirror image of chiral objects - a specific steroisomer.






2. Name for propanal






3. Propylenes attached to a backbone at the C-3 position. Meaning the double bond at end of the chain and single bonded carbon at rest






4. Highest energy no separation. or 120 separation.






5. What is produced when o3 with lialh4 or nabh4






6. Diborane add to double bond. boron acts as lewis acid and attaches to less hindered carbon. hydride transferred to adjacent carbon. antimarkonikov - alcohol produced






7. Spatial arrangement of the atoms or groups of a sterioisomer






8. What are the best leaving groups?






9. When boat flips






10. Most favorable of staggared conformations






11. Name for ethanal






12. Solvents with protons in solution - e.g. water or alcohol. large atoms tend to be better nucleophiles in here because they can shed the solvating protons around them and are more polarizable






13. In presence of peroxide - oxygen or ultraviolet light. antimarkonikov because they want a stable free radical. therefore X ends up on least subsituted carbon






14. Object that is not superimposable upon mirror image






15. Results when nonadjacent atoms or groups compete for space. dominant source of energy in flagpole interactions of the boat conformation. thus it goes in various conformations like chair boat and twist.






16. Electrons of pi bond are reactive and easily attacked by molecules that want e pair e.g. electrophiles.






17. Goal is to produce most stable carbocation

18. Name for mathanal






19. One s and two p 120 degree apart






20. Results when cyclic molecules must assume conformations that have eclipsed interactions






21. Chain of carbons connected by single bonds with hydrogen atoms attached.






22. Charged - need electrons






23. Di - tri - t - sec - n -






24. If a compound is able to rotate plane polarized light.






25. Carbon double bonded to an oxygen






26. Cleaves double bond in half - it only oxidizes the carbon to an aldehyde under reducing conditions. if ozidizing make same product as KMNO4






27. Three different substitutents often have plane of symmetry. and rotation of 180 will allow molecule to be superimposed on mirror image






28. Share molecular formula but have different chemical and physical properties






29. When two p orbitals line up in parallel and electron clouds overlap. it exsits over a single bond.






30. Diols with hydroxyl group on adjacent carbon






31. A sigma bond and two pi bonds






32. Carbon with four different substituents and lack a plane of symmetry






33. Not solvated






34. M - chloroperoxybenzoic acid






35. Two hydroxyl groups






36. Refers to the =CH2 group






37. Diol with hydroxyl group on same carbon






38. Contain carbon carbon double bonds. Use same root of alkane but end with 'ene'






39. E of double bond act as lewis base and react with hydrogen of hx. make carbocation intermediate. use markonikovs rule






40. A = observed rotation / concentration * length






41. Is bonded to only one other carbon atom






42. Use the Greek root for the number of carbons followed by the ending - - ane






43. Common name for ethyne






44. A molecule with an internal plane of symmetry






45. Creation of long - high molecular weight polymer composed of repeating subunit called monomers. occur through a radical mechanism.






46. How many stereoisomers can a molecule have with n chiral centers






47. Reaction of alkane with oxygen to form carbon dioxide - water and heat.






48. N - l - ml - ms






49. Y = position of double bond - x is position of triple bond - root is the prefix representing the length of the principal carbon chain






50. F - CL - Br - I
