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. Formed by mixing different types of orbitals






2. Name for mathanal






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






4. Two hydroxyl groups






5. What are the best leaving groups?






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






7. Functionality is specified by alkoxy- prefix. ROR






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






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






10. Steps of free radical substitution






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






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






13. What is produced when o3 with lialh4 or nabh4






14. M - chloroperoxybenzoic acid






15. Same chemical formula. same atomic connectivity . different in how atoms are arranged in space






16. Carbon double bonded to an oxygen






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






18. Carbon carbon triple bonds. Suffix-yne.






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






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. Alphabetical order of alkane rxn






22. 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.






23. Hydrocarbon with one or more carbon carbon triple bond






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

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






26. Charged - need electrons






27. Compounds with halogen






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






29. Same molecular formula but different structure






30. Object that is not superimposable upon mirror image






31. Lowest priority group projects into the page






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






33. Diols with hydroxyl group on adjacent carbon






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






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






36. Is bonded to only one other carbon atom






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






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






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






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






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






42. O3






43. Diol with hydroxyl group on same carbon






44. One s and two p 120 degree apart






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






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






47. 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






48. Combustion reaction occurs through a radical process






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






50. If reagent has a bunch of oxygen
