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






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






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






4. Refers to the =CH2 group






5. If reagent has a bunch of oxygen






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






7. Di - tri - t - sec - n -






8. Object that is not superimposable upon mirror image






9. When boat flips






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






11. A molecule with an internal plane of symmetry






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






13. What is produced when o3 with lialh4 or nabh4






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






15. A sigma bond and two pi bonds






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






17. Always receive number one. contain carbonyl and OH group - very oxidized. highest priority functional group.






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






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






20. 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.






21. Monosubstituted ethylene






22. M - chloroperoxybenzoic acid






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






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






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

26. Carbon double bonded to an oxygen






27. Most favorable of staggared conformations






28. When bond angles deviate from ideal values






29. 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-






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






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






32. Zn/h or CH3/s with ozonolysis






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






34. Is bonded to only one other carbon atom






35. 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.






36. Steps of free radical substitution






37. Formed by mixing different types of orbitals






38. Transfer of electrions from one atome to another






39. F - CL - Br - I






40. Diols with hydroxyl group on adjacent carbon






41. N - l - ml - ms






42. Kmno4






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






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






45. 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






46. Lowest priority group projects into the page






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






48. Two hydroxyl groups






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






50. Name for ethanal
