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. 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






2. A sigma bond and two pi bonds






3. 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






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






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






6. Monosubstituted ethylene






7. N - l - ml - ms






8. Alkene oxidized with this - strong oxidizing agent. CH3CO3H or mcpba and it makes epoxide or oxirane






9. Formed by mixing different types of orbitals






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






11. Combustion reaction occurs through a radical process






12. A molecule with an internal plane of symmetry






13. Cleaves double bond in half - it only oxidizes the carbon to an aldehyde under reducing conditions. if ozidizing make same product as KMNO4






14. Iso - neo - cyclo






15. What are the best leaving groups?






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






17. Charged - need electrons






18. One s and two p 120 degree apart






19. Common name for ethyne






20. Highest energy no separation. or 120 separation.






21. When boat flips






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






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






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






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






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






27. Lowest priority group projects into the page






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






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






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






31. F - CL - Br - I






32. Not solvated






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






34. Alphabetical order of alkane rxn






35. One s and three p orbitals






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






37. 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.






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






39. M - chloroperoxybenzoic acid






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






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






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






43. Diols with hydroxyl group on adjacent carbon






44. A = observed rotation / concentration * length






45. Methyl are 60 degrees apart. kinda stable






46. Two hydroxyl groups






47. Transfer of electrions from one atome to another






48. Goal is to produce most stable carbocation

49. Name for propanal






50. 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.
