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






2. Monosubstituted ethylene






3. Occur when a molecule is broken down by heat. used to reduce the avverage molecular weight of heavy oils. c - c - bonds are cleave dand make small chain alkyl radicals that recombine to form different alkanes






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






5. Common name for ethyne






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






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






8. Di - tri - t - sec - n -






9. One s and three p orbitals






10. When bond angles deviate from ideal values






11. Zn/h or CH3/s with ozonolysis






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






13. Functionality is specified by alkoxy- prefix. ROR






14. N - l - ml - ms






15. Highest energy no separation. or 120 separation.






16. Steps of free radical substitution






17. Same molecular formula but different structure






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






19. Name for mathanal






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






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






22. One s and two p 120 degree apart






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






24. Compounds with halogen






25. What is produced when o3 with lialh4 or nabh4






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






27. If reagent has a bunch of oxygen






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






29. Hydrocarbon with one or more carbon carbon triple bond






30. Sharing of electron between atoms






31. Most similar. same molecule only at different points in their rotation. show them with newmans projections






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






33. A molecule with an internal plane of symmetry






34. M - chloroperoxybenzoic acid






35. 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.






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






37. 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






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






39. Carbon carbon triple bonds. Suffix-yne.






40. 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






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






42. Diols with hydroxyl group on adjacent carbon






43. Is bonded to only one other carbon atom






44. What are the best leaving groups?






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

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






47. Transfer of electrions from one atome to another






48. Object that is not superimposable upon mirror image






49. 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






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