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






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






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






4. F - CL - Br - I






5. Iso - neo - cyclo






6. Refers to the =CH2 group






7. Di - tri - t - sec - n -






8. Carbon double bonded to an oxygen






9. Common name for ethyne






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






11. Name for mathanal






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






13. Compounds with halogen






14. Zn/h or CH3/s with ozonolysis






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






16. Charged - need electrons






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






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






19. 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






20. Hydrocarbon with one or more carbon carbon triple bond






21. 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.






22. Formed by mixing different types of orbitals






23. When bond angles deviate from ideal values






24. What are the best leaving groups?






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






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






27. 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






28. 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.






29. Lowest priority group projects into the page






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






31. Name for propanal






32. Rotations cancel each other out therefore no optical activity






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






34. A molecule with an internal plane of symmetry






35. 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-






36. In presence of peroxide - oxygen or ultraviolet light. antimarkonikov because they want a stable free radical. therefore X ends up on least subsituted carbon






37. Sharing of electron between atoms






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






39. A sigma bond and two pi bonds






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






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






42. Kmno4






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






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






45. Functionality is specified by alkoxy- prefix. ROR






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






47. When boat flips






48. Object that is not superimposable upon mirror image






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






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
