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. A molecule with an internal plane of symmetry






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






3. 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






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






5. Sharing of electron between atoms






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






7. N - l - ml - ms






8. 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-






9. Hydrocarbon with one or more carbon carbon triple bond






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






11. Carbon carbon triple bonds. Suffix-yne.






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






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






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






15. A = observed rotation / concentration * length






16. Object that is not superimposable upon mirror image






17. 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.






18. Methyl are 60 degrees apart. kinda stable






19. Carbon double bonded to an oxygen






20. Most favorable of staggared conformations






21. What are the best leaving groups?






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






23. Charged - need electrons






24. Compounds with halogen






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






26. 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






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






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






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






30. Monosubstituted ethylene






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






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






33. Name for propanal






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






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






36. F - CL - Br - I






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






38. Highest energy no separation. or 120 separation.






39. Transfer of electrions from one atome to another






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






41. When bond angles deviate from ideal values






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

43. Same molecular formula but different structure






44. 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.






45. Diols with hydroxyl group on adjacent carbon






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






47. Iso - neo - cyclo






48. Zn/h or CH3/s with ozonolysis






49. 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






50. What is produced when o3 with lialh4 or nabh4
