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. Carbon double bonded to an oxygen






3. Transfer of electrions from one atome to another






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






5. Rotations cancel each other out therefore no optical activity






6. Diols with hydroxyl group on adjacent carbon






7. Goal is to produce most stable carbocation

8. Not solvated






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

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






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






12. 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






13. Nitrogen containing compound - longest chain attached to nitrogen used in backbone. use e and replace with AMINE. if more complex molecule present - use prefix amino. IF additional group added - use N-






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






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






16. Arise from angle strain - torsional strian and nonbonded strain






17. Functionality is specified by alkoxy- prefix. ROR






18. Combustion reaction occurs through a radical process






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






20. 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.






21. Kmno4






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






23. What is produced when o3 with lialh4 or nabh4






24. A sigma bond and two pi bonds






25. 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






26. Nonterminal alkenes are cleaved to form two molar equivalent of carvoxylic acid ..make keton






27. Compounds with halogen






28. Monosubstituted ethylene






29. Steps of free radical substitution






30. O3






31. Diol with hydroxyl group on same carbon






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






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






34. A radical transfers a hydrogen atom to another radical and makes an alkane and alkene






35. If reagent has a bunch of oxygen






36. Lowest priority group projects into the page






37. Water can be added to alkenes under acidic conditions. make carbocation. ends with alcohol






38. Hydrocarbon with one or more carbon carbon triple bond






39. Methyl are 60 degrees apart. kinda stable






40. Two p orbital form pi and third p orbital combine with s to make two sp hybrid. 180 degree apart






41. One s and two p 120 degree apart






42. Alkene oxidized with this - strong oxidizing agent. CH3CO3H or mcpba and it makes epoxide or oxirane






43. Most favorable of staggared conformations






44. Carbon carbon triple bonds. Suffix-yne.






45. Formed by mixing different types of orbitals






46. M - chloroperoxybenzoic acid






47. Common name for ethyne






48. Carbonyl located in middle or somewhere in chane. Named with One






49. Is bonded to only one other carbon atom






50. Di - tri - t - sec - n -
