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. What are the best leaving groups?






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






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






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


5. What is produced when o3 with lialh4 or nabh4






6. Alkene oxidized with this - strong oxidizing agent. CH3CO3H or mcpba and it makes epoxide or oxirane






7. Refers to the =CH2 group






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






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






10. Object that is not superimposable upon mirror image






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






12. Rotations cancel each other out therefore no optical activity






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






14. M - chloroperoxybenzoic acid






15. Name for propanal






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






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






18. Kmno4






19. A sigma bond and two pi bonds






20. Name for ethanal






21. Goal is to produce most stable carbocation


22. 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






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






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






25. Combustion reaction occurs through a radical process






26. Monosubstituted ethylene






27. Functionality is specified by alkoxy- prefix. ROR






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






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






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. One s and two p 120 degree apart






32. A molecule with an internal plane of symmetry






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






34. 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.






35. Zn/h or CH3/s with ozonolysis






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






37. A = observed rotation / concentration * length






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






39. Carbon carbon triple bonds. Suffix-yne.






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






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






42. Diols with hydroxyl group on adjacent carbon






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






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






45. Highest energy no separation. or 120 separation.






46. Compounds with halogen






47. Methyl are 60 degrees apart. kinda stable






48. Alphabetical order of alkane rxn






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






50. Diol with hydroxyl group on same carbon
