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






2. Carbon carbon triple bonds. Suffix-yne.






3. Lowest priority group projects into the page






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






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






6. What is produced when o3 with lialh4 or nabh4






7. 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-






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






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






10. Is bonded to only one other carbon atom






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






12. Two hydroxyl groups






13. Diols with hydroxyl group on adjacent carbon






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






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






16. O3






17. Zn/h or CH3/s with ozonolysis






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






19. Common name for ethyne






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






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






22. Transfer of electrions from one atome to another






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






24. What are the best leaving groups?






25. Same molecular formula but different structure






26. One s and three p orbitals






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






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






29. Functionality is specified by alkoxy- prefix. ROR






30. 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






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






32. Diol with hydroxyl group on same carbon






33. 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






34. Highest energy no separation. or 120 separation.






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






36. Monosubstituted ethylene






37. Iso - neo - cyclo






38. A molecule with an internal plane of symmetry






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






40. 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.






41. Most favorable of staggared conformations






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






43. Object that is not superimposable upon mirror image






44. Alphabetical order of alkane rxn






45. When boat flips






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






47. Name for mathanal






48. If reagent has a bunch of oxygen






49. Combustion reaction occurs through a radical process






50. Di - tri - t - sec - n -
