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. Refers to the =CH2 group






2. Carbon double bonded to an oxygen






3. Common name for ethyne






4. Is bonded to only one other carbon atom






5. A = observed rotation / concentration * length






6. Diols with hydroxyl group on adjacent carbon






7. 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






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






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






10. Highest energy no separation. or 120 separation.






11. Name for propanal






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






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






14. What are the best leaving groups?






15. Name for mathanal






16. Hydrocarbon with one or more carbon carbon triple bond






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






18. Two hydroxyl groups






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






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






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






22. M - chloroperoxybenzoic acid






23. Iso - neo - cyclo






24. 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






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






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






27. If reagent has a bunch of oxygen






28. 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.






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






30. Monosubstituted ethylene






31. F - CL - Br - I






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






33. When boat flips






34. Name for ethanal






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






36. One s and two p 120 degree apart






37. 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-






38. Rotations cancel each other out therefore no optical activity






39. Charged - need electrons






40. Not solvated






41. One s and three p orbitals






42. A molecule with an internal plane of symmetry






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

44. Steps of free radical substitution






45. Alkenes oxidzed with kmno4 - if made with cold - dilue - make OH on each side of double bond - diols or glycol in syn orientation






46. Goal is to produce most stable carbocation

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






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






49. Most favorable of staggared conformations






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