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. Diol with hydroxyl group on same carbon






2. Kmno4






3. Iso - neo - cyclo






4. Refers to the =CH2 group






5. In which one or morehydrogen atoms are replaced with a halogen atom. via free radical substitution






6. Most favorable of staggared conformations






7. Carbon with four different substituents and lack a plane of symmetry






8. A sigma bond and two pi bonds






9. Methyl are 60 degrees apart. kinda stable






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

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






12. Sharing of electron between atoms






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






14. 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






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






16. Charged - need electrons






17. Diols with hydroxyl group on adjacent carbon






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






19. 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-






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






21. 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.






22. Highest energy no separation. or 120 separation.






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






24. 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






25. Two hydroxyl groups






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






27. M - chloroperoxybenzoic acid






28. Transfer of electrions from one atome to another






29. Compounds with halogen






30. Common name for ethyne






31. Carbon carbon triple bonds. Suffix-yne.






32. When bond angles deviate from ideal values






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






34. 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.






35. 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






36. Nonterminal alkenes are cleaved to form two molar equivalent of carvoxylic acid ..make keton






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






38. One s and two p 120 degree apart






39. Same molecular formula but different structure






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






41. Lowest priority group projects into the page






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






43. Goal is to produce most stable carbocation

44. When boat flips






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






46. Hydrocarbon with one or more carbon carbon triple bond






47. Steps of free radical substitution






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






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






50. Formed by mixing different types of orbitals
