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. Steps of free radical substitution






2. Methyl are 60 degrees apart. kinda stable






3. Object that is not superimposable upon mirror image






4. Carbon carbon triple bonds. Suffix-yne.






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






6. A sigma bond and two pi bonds






7. Alphabetical order of alkane rxn






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






9. Functionality is specified by alkoxy- prefix. ROR






10. F - CL - Br - I






11. Combustion reaction occurs through a radical process






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






13. Name for propanal






14. Water can be added to alkenes under acidic conditions. make carbocation. ends with alcohol






15. M - chloroperoxybenzoic acid






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






17. 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






18. Occur when a molecule is broken down by heat. used to reduce the avverage molecular weight of heavy oils. c - c - bonds are cleave dand make small chain alkyl radicals that recombine to form different alkanes






19. Diol with hydroxyl group on same carbon






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






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






22. Lowest priority group projects into the page






23. Most favorable of staggared conformations






24. Iso - neo - cyclo






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






26. Common name for ethyne






27. No double bonds. it has the maximum number of hydrogens.






28. Monosubstituted ethylene






29. Sharing of electron between atoms






30. What are the best leaving groups?






31. 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






32. Zn/h or CH3/s with ozonolysis






33. What is produced when o3 with lialh4 or nabh4






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






35. One s and two p 120 degree apart






36. Compounds with halogen






37. Formed by mixing different types of orbitals






38. Two hydroxyl groups






39. Charged - need electrons






40. 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.






41. Highest energy no separation. or 120 separation.






42. O3






43. Is bonded to only one other carbon atom






44. 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-






45. If reagent has a bunch of oxygen






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






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






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






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






50. N - l - ml - ms
