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. 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






2. Highest energy no separation. or 120 separation.






3. One s and two p 120 degree apart






4. Object that is not superimposable upon mirror image






5. Describes the exact spatial arrangement of groups of atoms independent of other molecules.






6. One s and three p orbitals






7. Nucleus lover. electron rich species that are attracked to charged atoms






8. Palladium or barium sulfate (BaSO4) with quinoline. occur on metal surface - make cis.

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






10. Name for mathanal






11. Charged - need electrons






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






13. O3






14. Formed by mixing different types of orbitals






15. N - l - ml - ms






16. Is bonded to only one other carbon atom






17. What is produced when o3 with lialh4 or nabh4






18. Differ in position of substitutents attached to a double bond or cycloalkane. Cis or trans or e or z






19. 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






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






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






22. Two hydroxyl groups






23. Carbonyl located at the end of the chain named by replacing al with e. e.g. butanal






24. Same chemical formula. same atomic connectivity . different in how atoms are arranged in space






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






26. Ozonolysis under hot acidic kmO4 - e.g. H2O2 condition






27. Reducing an alkene by adding molecular hydrogen to double bond with aid of metal catalyst. e.g. pt - pd - ni. takes place on surface of metal so it does syn addition






28. Hydrocarbon with one or more carbon carbon triple bond






29. Name for propanal






30. When boat flips






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






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






33. More likely it is to attract positively charged proton. nucleophilic strength decreses: RO->HO>RCO2>ROH>H2O






34. Moleculse that have the opposite configuration at their one chiral center. or if multiple chiral centers - must have the opposite configuration at every one of their chiral centers to be enantiomers. identical physical properties and much of the same






35. Diols with hydroxyl group on adjacent carbon






36. Same molecular formula but different structure






37. Non mirror image of configurational isomers. cis and trans alkenes are them. possible when a molecule has two or more stereogenic centers that differ at some but not alll of the centers. they require multiple chiral centers.






38. Monosubstituted ethylene






39. Lowest priority group projects into the page






40. Not solvated






41. A molecule with an internal plane of symmetry






42. Fast process. double bond is nucleophile and attack x2. make cyclic halonium ion with either br or cl. and make dihalo trans






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






44. Configuration in relation to another chiral molecule. use it to determine if a molecule is an enantiomer - diastereomer - etc






45. M - chloroperoxybenzoic acid






46. Rotations cancel each other out therefore no optical activity






47. Iso - neo - cyclo






48. Always receive number one. contain carbonyl and OH group - very oxidized. highest priority functional group.






49. Combustion reaction occurs through a radical process






50. Most favorable of staggared conformations
