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






2. If reagent has a bunch of oxygen






3. 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.






4. Refers to the =CH2 group






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






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






7. Most favorable of staggared conformations






8. Monosubstituted ethylene






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






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






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






12. Transfer of electrions from one atome to another






13. Common name for ethyne






14. A molecule with an internal plane of symmetry






15. F - CL - Br - I






16. Iso - neo - cyclo






17. Not solvated






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






19. N - l - ml - ms






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






21. 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.






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






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






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






25. Object that is not superimposable upon mirror image






26. A sigma bond and two pi bonds






27. Kmno4






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






29. Di - tri - t - sec - n -






30. Carbon double bonded to an oxygen






31. M - chloroperoxybenzoic acid






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






33. Carbon carbon triple bonds. Suffix-yne.






34. Compounds with halogen






35. One s and two p 120 degree apart






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






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






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






39. Steps of free radical substitution






40. 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.






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






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






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






44. A = observed rotation / concentration * length






45. How many stereoisomers can a molecule have with n chiral centers






46. Diols with hydroxyl group on adjacent carbon






47. Methyl are 60 degrees apart. kinda stable






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






49. Same molecular formula but different structure






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