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






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






3. Formed by mixing different types of orbitals






4. Spatial arrangement of the atoms or groups of a sterioisomer






5. One s and two p 120 degree apart






6. Rotations cancel each other out therefore no optical activity






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. Di - tri - t - sec - n -






9. Methyl are 60 degrees apart. kinda stable






10. Charged - need electrons






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






12. A molecule with an internal plane of symmetry






13. 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.






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






15. Highest energy no separation. or 120 separation.






16. 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






17. Lowest priority group projects into the page






18. Alphabetical order of alkane rxn






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

20. 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.






21. O3






22. Carbon carbon triple bonds. Suffix-yne.






23. Kmno4






24. 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






25. M - chloroperoxybenzoic acid






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






27. What is produced when o3 with lialh4 or nabh4






28. A = observed rotation / concentration * length






29. Functionality is specified by alkoxy- prefix. ROR






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






31. Zn/h or CH3/s with ozonolysis






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






33. N - l - ml - ms






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






35. Diols with hydroxyl group on adjacent carbon






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






37. Goal is to produce most stable carbocation

38. Object that is not superimposable upon mirror image






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






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






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






42. Arise from angle strain - torsional strian and nonbonded strain






43. Same molecular formula but different structure






44. Describes the exact spatial arrangement of groups of atoms independent of other molecules.






45. 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






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






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






48. Diol with hydroxyl group on same carbon






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






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