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






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






3. Refers to the =CH2 group






4. Combustion reaction occurs through a radical process






5. Rotations cancel each other out therefore no optical activity






6. Name for ethanal






7. 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.






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






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






10. Functionality is specified by alkoxy- prefix. ROR






11. O3






12. N - l - ml - ms






13. One s and two p 120 degree apart






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






15. Highest energy no separation. or 120 separation.






16. Name for mathanal






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






18. A molecule with an internal plane of symmetry






19. Two hydroxyl groups






20. A sigma bond and two pi bonds






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






22. 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.






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






24. Is bonded to only one other carbon atom






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






26. Not solvated






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






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






29. What are the best leaving groups?






30. Hydrocarbon with one or more carbon carbon triple bond






31. Carbon double bonded to an oxygen






32. 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






33. 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-






34. Alphabetical order of alkane rxn






35. Monosubstituted ethylene






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






37. Kmno4






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






39. Compounds with halogen






40. One s and three p orbitals






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






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






43. Charged - need electrons






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






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


46. Sharing of electron between atoms






47. If reagent has a bunch of oxygen






48. Iso - neo - cyclo






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






50. Object that is not superimposable upon mirror image
