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. 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






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






3. Steps of free radical substitution






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






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

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






7. Rotations cancel each other out therefore no optical activity






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






9. What is produced when o3 with lialh4 or nabh4






10. Non mirror image of configurational isomers. cis and trans alkenes are them. possible when a molecule has two or more stereogenic centers that differ at some but not alll of the centers. they require multiple chiral centers.






11. Is bonded to only one other carbon atom






12. A = observed rotation / concentration * length






13. A molecule with an internal plane of symmetry






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






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






16. Alphabetical order of alkane rxn






17. Object that is not superimposable upon mirror image






18. Combustion reaction occurs through a radical process






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






20. Highest energy no separation. or 120 separation.






21. Compounds with halogen






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






23. Common name for ethyne






24. Name for ethanal






25. 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






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






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






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






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






30. Carbon double bonded to an oxygen






31. Carbon carbon triple bonds. Suffix-yne.






32. Di - tri - t - sec - n -






33. Methyl are 60 degrees apart. kinda stable






34. Lowest priority group projects into the page






35. Not solvated






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






37. 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






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






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






40. Name for propanal






41. A sigma bond and two pi bonds






42. 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






43. Refers to the =CH2 group






44. What are the best leaving groups?






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






46. F - CL - Br - I






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






48. Zn/h or CH3/s with ozonolysis






49. Monosubstituted ethylene






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