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






2. A molecule with an internal plane of symmetry






3. Steps of free radical substitution






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






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






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






7. 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.






8. Diols with hydroxyl group on adjacent carbon






9. Is bonded to only one other carbon atom






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

11. Charged - need electrons






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






13. When boat flips






14. Functionality is specified by alkoxy- prefix. ROR






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






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






17. Name for ethanal






18. Lowest priority group projects into the page






19. Y = position of double bond - x is position of triple bond - root is the prefix representing the length of the principal carbon chain






20. F - CL - Br - I






21. 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.






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






23. O3






24. Transfer of electrions from one atome to another






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






26. 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






27. Combustion reaction occurs through a radical process






28. Object that is not superimposable upon mirror image






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






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






31. One s and three p orbitals






32. Carbon double bonded to an oxygen






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






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






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






36. Alphabetical order of alkane rxn






37. N - l - ml - ms






38. Formed by mixing different types of orbitals






39. A = observed rotation / concentration * length






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






41. Two hydroxyl groups






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






43. What are the best leaving groups?






44. One s and two p 120 degree apart






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






46. Most favorable of staggared conformations






47. Results when cyclic molecules must assume conformations that have eclipsed interactions






48. Iso - neo - cyclo






49. Rotations cancel each other out therefore no optical activity






50. Methyl are 60 degrees apart. kinda stable
