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. Refers to the =CH2 group






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






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






4. Name for ethanal






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






6. One s and two p 120 degree apart






7. Carbon carbon triple bonds. Suffix-yne.






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






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

10. What are the best leaving groups?






11. In presence of peroxide - oxygen or ultraviolet light. antimarkonikov because they want a stable free radical. therefore X ends up on least subsituted carbon






12. Formed by mixing different types of orbitals






13. What is produced when o3 with lialh4 or nabh4






14. Alphabetical order of alkane rxn






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






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. 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






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






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






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






21. Same molecular formula but different structure






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






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






24. Steps of free radical substitution






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






26. Zn/h or CH3/s with ozonolysis






27. 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.






28. When boat flips






29. Kmno4






30. Carbonyl located at the end of the chain named by replacing al with e. e.g. butanal






31. One s and three p orbitals






32. Combustion reaction occurs through a radical process






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






34. O3






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






36. Common name for ethyne






37. Monosubstituted ethylene






38. 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






39. If reagent has a bunch of oxygen






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






41. Functionality is specified by alkoxy- prefix. ROR






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






43. A = observed rotation / concentration * length






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






45. Two hydroxyl groups






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






47. Methyl are 60 degrees apart. kinda stable






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






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






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