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






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






3. Combustion reaction occurs through a radical process






4. When boat flips






5. Methyl are 60 degrees apart. kinda stable






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






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






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






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






10. If reagent has a bunch of oxygen






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






12. Most favorable of staggared conformations






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






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






15. A molecule with an internal plane of symmetry






16. Diol with hydroxyl group on same carbon






17. Kmno4






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






19. Goal is to produce most stable carbocation

20. Name for ethanal






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






22. Alphabetical order of alkane rxn






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






24. Monosubstituted ethylene






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






26. N - l - ml - ms






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

28. F - CL - Br - I






29. Functionality is specified by alkoxy- prefix. ROR






30. A sigma bond and two pi bonds






31. Same molecular formula but different structure






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






33. Formed by mixing different types of orbitals






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






35. Not solvated






36. Name for mathanal






37. Rotations cancel each other out therefore no optical activity






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






39. Charged - need electrons






40. Carbon carbon triple bonds. Suffix-yne.






41. Hydrocarbon with one or more carbon carbon triple bond






42. Object that is not superimposable upon mirror image






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






44. 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.






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. Sharing of electron between atoms






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






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






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






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