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. Lowest priority group projects into the page






2. Most favorable of staggared conformations






3. Compounds with halogen






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






5. 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






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






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






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






9. F - CL - Br - I






10. One s and three p orbitals






11. One s and two p 120 degree apart






12. Carbon carbon triple bonds. Suffix-yne.






13. Transfer of electrions from one atome to another






14. Methyl are 60 degrees apart. kinda stable






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






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






17. Water can be added to alkenes under acidic conditions. make carbocation. ends with alcohol






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






19. 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






20. Object that is not superimposable upon mirror image






21. 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-






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






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






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






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






26. Combustion reaction occurs through a radical process






27. Name for ethanal






28. Two hydroxyl groups






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






30. Hydrocarbon with one or more carbon carbon triple bond






31. 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.






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






33. Alphabetical order of alkane rxn






34. What are the best leaving groups?






35. Diols with hydroxyl group on adjacent carbon






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






37. Monosubstituted ethylene






38. Iso - neo - cyclo






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






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


41. Sharing of electron between atoms






42. Di - tri - t - sec - n -






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






44. 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.






45. Name for mathanal






46. A = observed rotation / concentration * length






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






48. Is bonded to only one other carbon atom






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






50. Goal is to produce most stable carbocation
