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. Sharing of electron between atoms






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






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

4. Functionality is specified by alkoxy- prefix. ROR






5. What are the best leaving groups?






6. Common name for ethyne






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






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






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






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






12. Kmno4






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






14. Not solvated






15. Iso - neo - cyclo






16. Diol with hydroxyl group on same carbon






17. A = observed rotation / concentration * length






18. Di - tri - t - sec - n -






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






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






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






22. Object that is not superimposable upon mirror image






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






24. O3






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






26. Alphabetical order of alkane rxn






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






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






29. One s and two p 120 degree apart






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






31. Formed by mixing different types of orbitals






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






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






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






35. When boat flips






36. 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






37. Hydrocarbon with one or more carbon carbon triple bond






38. Most favorable of staggared conformations






39. Rotations cancel each other out therefore no optical activity






40. Two hydroxyl groups






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






42. Name for ethanal






43. If reagent has a bunch of oxygen






44. One s and three p orbitals






45. Lowest priority group projects into the page






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






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






48. Name for propanal






49. Steps of free radical substitution






50. 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.
