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. 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.






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






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






4. A = observed rotation / concentration * length






5. Not solvated






6. Monosubstituted ethylene






7. Functionality is specified by alkoxy- prefix. ROR






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






9. Charged - need electrons






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






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






12. Highest energy no separation. or 120 separation.






13. Carbon carbon triple bonds. Suffix-yne.






14. A molecule with an internal plane of symmetry






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






16. When two p orbitals line up in parallel and electron clouds overlap. it exsits over a single bond.






17. What is produced when o3 with lialh4 or nabh4






18. Name for propanal






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






20. If reagent has a bunch of oxygen






21. Two hydroxyl groups






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






23. Formed by mixing different types of orbitals






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






25. Refers to the =CH2 group






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






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






28. Name for mathanal






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






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






31. One s and three p orbitals






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






33. N - l - ml - ms






34. Diols with hydroxyl group on adjacent carbon






35. Chain of carbons connected by single bonds with hydrogen atoms attached.






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






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






38. What are the best leaving groups?






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






40. Object that is not superimposable upon mirror image






41. Fast process. double bond is nucleophile and attack x2. make cyclic halonium ion with either br or cl. and make dihalo trans






42. Name for ethanal






43. Same molecular formula but different structure






44. Methyl are 60 degrees apart. kinda stable






45. Kmno4






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






47. 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-






48. Iso - neo - cyclo






49. Hydrocarbon with one or more carbon carbon triple bond






50. M - chloroperoxybenzoic acid
