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. Lowest priority group projects into the page






2. Zn/h or CH3/s with ozonolysis






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






4. 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.






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






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






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






8. Carbon carbon triple bonds. Suffix-yne.






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






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






11. Diol with hydroxyl group on same carbon






12. Hydrocarbon with one or more carbon carbon triple bond






13. 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






14. Sharing of electron between atoms






15. A sigma bond and two pi bonds






16. Goal is to produce most stable carbocation

17. Object that is not superimposable upon mirror image






18. No double bonds. it has the maximum number of hydrogens.






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






21. Steps of free radical substitution






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






23. Methyl are 60 degrees apart. kinda stable






24. Transfer of electrions from one atome to another






25. Diols with hydroxyl group on adjacent carbon






26. 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






27. If reagent has a bunch of oxygen






28. Charged - need electrons






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






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






31. Is bonded to only one other carbon atom






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






33. Combustion reaction occurs through a radical process






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






35. What is produced when o3 with lialh4 or nabh4






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






37. When two atomic orbitals combine. obtained mathematically by adding or subtracting wave functions. if sings are the same - make bonding - if different - less stable antibonding.






38. When bond angles deviate from ideal values






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






40. Highest energy no separation. or 120 separation.






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






42. Name for propanal






43. Name for mathanal






44. In which one or morehydrogen atoms are replaced with a halogen atom. via free radical substitution






45. O3






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






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






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

49. One s and three p orbitals






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