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. Zn/h or CH3/s with ozonolysis






2. Is bonded to only one other carbon atom






3. 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-






4. What are the best leaving groups?






5. A = observed rotation / concentration * length






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

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






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






9. Methyl are 60 degrees apart. kinda stable






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






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






12. Goal is to produce most stable carbocation

13. Name for ethanal






14. 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






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






16. Carbon carbon triple bonds. Suffix-yne.






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






18. Diols with hydroxyl group on adjacent carbon






19. Refers to the =CH2 group






20. Same molecular formula but different structure






21. Transfer of electrions from one atome to another






22. Compounds with halogen






23. Most favorable of staggared conformations






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






25. Common name for ethyne






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






27. Formed by mixing different types of orbitals






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






29. 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.






30. O3






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






32. Hydrocarbon with one or more carbon carbon triple bond






33. When a molecular orbital is formed head to head or tail to tail. all single bonds are tehese.






34. Di - tri - t - sec - n -






35. If reagent has a bunch of oxygen






36. What is produced when o3 with lialh4 or nabh4






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






38. N - l - ml - ms






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






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






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






42. Alphabetical order of alkane rxn






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






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






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






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






47. Creation of long - high molecular weight polymer composed of repeating subunit called monomers. occur through a radical mechanism.






48. Charged - need electrons






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






50. 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.
