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. Not solvated






2. Transfer of electrions from one atome to another






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






4. N - l - ml - ms






5. O3






6. 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-






7. Formed by mixing different types of orbitals






8. 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






9. Common name for ethyne






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






11. Combustion reaction occurs through a radical process






12. Compounds with halogen






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






14. A sigma bond and two pi bonds






15. F - CL - Br - I






16. Diol with hydroxyl group on same carbon






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






18. If reagent has a bunch of oxygen






19. Share molecular formula but have different chemical and physical properties






20. One s and two p 120 degree apart






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






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






23. 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.






24. A molecule with an internal plane of symmetry






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






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






27. Name for ethanal






28. Alphabetical order of alkane rxn






29. Refers to the =CH2 group






30. Methyl are 60 degrees apart. kinda stable






31. Two hydroxyl groups






32. Name for mathanal






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






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






35. Hydrocarbon with one or more carbon carbon triple bond






36. Charged - need electrons






37. Zn/h or CH3/s with ozonolysis






38. What is produced when o3 with lialh4 or nabh4






39. Functionality is specified by alkoxy- prefix. ROR






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






41. Goal is to produce most stable carbocation

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. Diols with hydroxyl group on adjacent carbon






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






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






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






47. Highest energy no separation. or 120 separation.






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






49. 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






50. Is bonded to only one other carbon atom
