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. Arise from angle strain - torsional strian and nonbonded strain






2. When boat flips






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






4. Highest energy no separation. or 120 separation.






5. 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






6. Diol with hydroxyl group on same carbon






7. Carbon carbon triple bonds. Suffix-yne.






8. Carbon double bonded to an oxygen






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






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






11. O3






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






13. Most favorable of staggared conformations






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






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






16. Name for mathanal






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






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






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






20. A sigma bond and two pi bonds






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






22. Refers to the =CH2 group






23. F - CL - Br - I






24. Nonterminal alkenes are cleaved to form two molar equivalent of carvoxylic acid ..make keton






25. Name for propanal






26. A molecule with an internal plane of symmetry






27. Object that is not superimposable upon mirror image






28. Monosubstituted ethylene






29. Goal is to produce most stable carbocation

30. Alphabetical order of alkane rxn






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






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






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






34. Name for ethanal






35. Di - tri - t - sec - n -






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






37. Lowest priority group projects into the page






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






39. Kmno4






40. Zn/h or CH3/s with ozonolysis






41. 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






42. One s and two p 120 degree apart






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






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






45. Compounds with halogen






46. Not solvated






47. Common name for ethyne






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






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






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