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. 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.






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






4. Lowest priority group projects into the page






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






6. M - chloroperoxybenzoic acid






7. When boat flips






8. What are the best leaving groups?






9. Sharing of electron between atoms






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






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






12. Alphabetical order of alkane rxn






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






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






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






16. Combustion reaction occurs through a radical process






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






18. 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






19. 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.






20. Compounds with halogen






21. Charged - need electrons






22. Monosubstituted ethylene






23. Object that is not superimposable upon mirror image






24. One s and two p 120 degree apart






25. 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






26. A molecule with an internal plane of symmetry






27. Zn/h or CH3/s with ozonolysis






28. Three different substitutents often have plane of symmetry. and rotation of 180 will allow molecule to be superimposed on mirror image






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






30. If reagent has a bunch of oxygen






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






32. Functionality is specified by alkoxy- prefix. ROR






33. Name for propanal






34. Not solvated






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






36. 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






37. A = observed rotation / concentration * length






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






39. O3






40. Carbon double bonded to an oxygen






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






42. 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-






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






44. F - CL - Br - I






45. Same molecular formula but different structure






46. Diol with hydroxyl group on same carbon






47. Two hydroxyl groups






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






49. N - l - ml - ms






50. Goal is to produce most stable carbocation
