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






2. N - l - ml - ms






3. Not solvated






4. Carbon double bonded to an oxygen






5. Charged - need electrons






6. Zn/h or CH3/s with ozonolysis






7. Diol with hydroxyl group on same carbon






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






9. Alphabetical order of alkane rxn






10. 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






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






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






13. Name for ethanal






14. Carbonyl located at the end of the chain named by replacing al with e. e.g. butanal






15. 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.






16. Transfer of electrions from one atome to another






17. Propylenes attached to a backbone at the C-3 position. Meaning the double bond at end of the chain and single bonded carbon at rest






18. Refers to the =CH2 group






19. Same molecular formula but different structure






20. Compounds with halogen






21. Goal is to produce most stable carbocation

22. Monosubstituted ethylene






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






24. Diols with hydroxyl group on adjacent carbon






25. Electrons of pi bond are reactive and easily attacked by molecules that want e pair e.g. electrophiles.






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






27. Di - tri - t - sec - n -






28. 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






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






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






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






32. One s and two p 120 degree apart






33. If reagent has a bunch of oxygen






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






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






36. Two hydroxyl groups






37. Combustion reaction occurs through a radical process






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






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






40. A sigma bond and two pi bonds






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






42. Formed by mixing different types of orbitals






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






44. What are the best leaving groups?






45. Carbon carbon triple bonds. Suffix-yne.






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






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






48. Is bonded to only one other carbon atom






49. 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.






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