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. Goal is to produce most stable carbocation

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


2. Charged - need electrons






3. 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.






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






5. One s and three p orbitals






6. O3






7. N - l - ml - ms






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






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






10. Steps of free radical substitution






11. 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






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






13. Combustion reaction occurs through a radical process






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






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






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






17. Diols with hydroxyl group on adjacent carbon






18. Iso - neo - cyclo






19. What is produced when o3 with lialh4 or nabh4






20. If reagent has a bunch of oxygen






21. Name for ethanal






22. Alphabetical order of alkane rxn






23. A sigma bond and two pi bonds






24. Name for mathanal






25. M - chloroperoxybenzoic acid






26. Carbon carbon triple bonds. Suffix-yne.






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






28. Name for propanal






29. 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-






30. Not solvated






31. When boat flips






32. Formed by mixing different types of orbitals






33. A = observed rotation / concentration * length






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






35. Highest energy no separation. or 120 separation.






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






37. When bond angles deviate from ideal values






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






39. F - CL - Br - I






40. A molecule with an internal plane of symmetry






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






42. Lowest priority group projects into the page






43. Common name for ethyne






44. Most favorable of staggared conformations






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






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






47. One s and two p 120 degree apart






48. Di - tri - t - sec - n -






49. Hydrocarbon with one or more carbon carbon triple bond






50. Occur when a molecule is broken down by heat. used to reduce the avverage molecular weight of heavy oils. c - c - bonds are cleave dand make small chain alkyl radicals that recombine to form different alkanes
