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. Methyl are 60 degrees apart. kinda stable






2. N - l - ml - ms






3. Compounds with halogen






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






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






6. Carbon double bonded to an oxygen






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






8. One s and two p 120 degree apart






9. Carbon carbon triple bonds. Suffix-yne.






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






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






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






13. If reagent has a bunch of oxygen






14. 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.






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






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






17. O3






18. 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






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






20. 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






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






22. Most favorable of staggared conformations






23. Monosubstituted ethylene






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






25. Formed by mixing different types of orbitals






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






27. What are the best leaving groups?






28. Zn/h or CH3/s with ozonolysis






29. Is bonded to only one other carbon atom






30. When bond angles deviate from ideal values






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

32. Highest energy no separation. or 120 separation.






33. 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-






34. 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.






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






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






37. Refers to the =CH2 group






38. 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.






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






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






41. Hydrocarbon with one or more carbon carbon triple bond






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






43. Kmno4






44. Common name for ethyne






45. Rotations cancel each other out therefore no optical activity






46. Charged - need electrons






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






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






49. Diol with hydroxyl group on same carbon






50. Functionality is specified by alkoxy- prefix. ROR
