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. Carbon double bonded to an oxygen






2. Monosubstituted ethylene






3. Compounds with halogen






4. 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






5. Diol with hydroxyl group on same carbon






6. One s and three p orbitals






7. Hydrocarbon with one or more carbon carbon triple bond






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






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






10. 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.






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






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






13. Reducing an alkene by adding molecular hydrogen to double bond with aid of metal catalyst. e.g. pt - pd - ni. takes place on surface of metal so it does syn addition






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






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






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

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






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






19. Formed by mixing different types of orbitals






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






21. Charged - need electrons






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






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






24. Alphabetical order of alkane rxn






25. Refers to the =CH2 group






26. Transfer of electrions from one atome to another






27. F - CL - Br - I






28. Two hydroxyl groups






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






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






31. N - l - ml - ms






32. Not solvated






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






34. Kmno4






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






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






37. Object that is not superimposable upon mirror image






38. M - chloroperoxybenzoic acid






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






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






41. Goal is to produce most stable carbocation

42. What are the best leaving groups?






43. If reagent has a bunch of oxygen






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






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






46. Name for ethanal






47. Iso - neo - cyclo






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






49. O3






50. Same molecular formula but different structure
