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. Steps of free radical substitution






2. When boat flips






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






4. Rotations cancel each other out therefore no optical activity






5. Two hydroxyl groups






6. When bond angles deviate from ideal values






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






8. 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






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






10. Alphabetical order of alkane rxn






11. 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.






12. Carbon double bonded to an oxygen






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






14. A molecule with an internal plane of symmetry






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






16. Nitrogen containing compound - longest chain attached to nitrogen used in backbone. use e and replace with AMINE. if more complex molecule present - use prefix amino. IF additional group added - use N-






17. Combustion reaction occurs through a radical process






18. N - l - ml - ms






19. Sharing of electron between atoms






20. Goal is to produce most stable carbocation

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






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






23. 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.






24. Hydrocarbon with one or more carbon carbon triple bond






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






26. What is produced when o3 with lialh4 or nabh4






27. What are the best leaving groups?






28. Object that is not superimposable upon mirror image






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






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






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






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






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






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

35. Di - tri - t - sec - n -






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






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






38. One s and two p 120 degree apart






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






40. Same molecular formula but different structure






41. Monosubstituted ethylene






42. Common name for ethyne






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






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






45. Highest energy no separation. or 120 separation.






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






47. Is bonded to only one other carbon atom






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






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






50. Zn/h or CH3/s with ozonolysis
