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. 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






2. Most favorable of staggared conformations






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






4. Monosubstituted ethylene






5. Combustion reaction occurs through a radical process






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






7. Zn/h or CH3/s with ozonolysis






8. Diols with hydroxyl group on adjacent carbon






9. F - CL - Br - I






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






11. A molecule with an internal plane of symmetry






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






13. 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.






14. 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






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






16. 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






17. Lowest priority group projects into the page






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






19. Common name for ethyne






20. What are the best leaving groups?






21. Name for propanal






22. 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






23. Not solvated






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






25. Fast process. double bond is nucleophile and attack x2. make cyclic halonium ion with either br or cl. and make dihalo trans






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






27. Rotations cancel each other out therefore no optical activity






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






29. Hydrocarbon with one or more carbon carbon triple bond






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






31. Compounds with halogen






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






33. Carbon carbon triple bonds. Suffix-yne.






34. A = observed rotation / concentration * length






35. Is bonded to only one other carbon atom






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






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






38. One s and three p orbitals






39. Name for ethanal






40. Diol with hydroxyl group on same carbon






41. Formed by mixing different types of orbitals






42. Highest energy no separation. or 120 separation.






43. Di - tri - t - sec - n -






44. Sharing of electron between atoms






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






46. Methyl are 60 degrees apart. kinda stable






47. Carbon double bonded to an oxygen






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






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






50. 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.
