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. Palladium or barium sulfate (BaSO4) with quinoline. occur on metal surface - make cis.


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






3. Same molecular formula but different structure






4. Two hydroxyl groups






5. When a molecular orbital is formed head to head or tail to tail. all single bonds are tehese.






6. Compounds with halogen






7. Diol with hydroxyl group on same carbon






8. A = observed rotation / concentration * length






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






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. N - l - ml - ms






12. Transfer of electrions from one atome to another






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






14. What are the best leaving groups?






15. 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






16. 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






17. Monosubstituted ethylene






18. Zn/h or CH3/s with ozonolysis






19. One s and two p 120 degree apart






20. F - CL - Br - I






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






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






23. A molecule with an internal plane of symmetry






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






25. What is produced when o3 with lialh4 or nabh4






26. Name for mathanal






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






28. Steps of free radical substitution






29. Carbon carbon triple bonds. Suffix-yne.






30. 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






31. Refers to the =CH2 group






32. A sigma bond and two pi bonds






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






34. Alphabetical order of alkane rxn






35. Diols with hydroxyl group on adjacent carbon






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






37. Di - tri - t - sec - n -






38. Kmno4






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






40. 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.






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






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






44. Name for propanal






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






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






47. Not solvated






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






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






50. Formed by mixing different types of orbitals
