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. Two hydroxyl groups






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






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






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






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






6. When bond angles deviate from ideal values






7. What is produced when o3 with lialh4 or nabh4






8. Is bonded to only one other carbon atom






9. Zn/h or CH3/s with ozonolysis






10. 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-






11. If reagent has a bunch of oxygen






12. Same molecular formula but different structure






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






14. Alphabetical order of alkane rxn






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






16. Name for mathanal






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






18. 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






19. Rotations cancel each other out therefore no optical activity






20. Carbon carbon triple bonds. Suffix-yne.






21. Common name for ethyne






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






23. F - CL - Br - I






24. When boat flips






25. Contain carbon carbon double bonds. Use same root of alkane but end with 'ene'






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






27. Monosubstituted ethylene






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






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






30. Name for ethanal






31. Kmno4






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






33. What are the best leaving groups?






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






35. Reducing an alkene by adding molecular hydrogen to double bond with aid of metal catalyst. e.g. pt - pd - ni. takes place on surface of metal so it does syn addition






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






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






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






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






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






41. Carbon double bonded to an oxygen






42. Functionality is specified by alkoxy- prefix. ROR






43. 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.






44. Transfer of electrions from one atome to another






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






46. A = observed rotation / concentration * length






47. O3






48. Formed by mixing different types of orbitals






49. Combustion reaction occurs through a radical process






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