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. A molecule with an internal plane of symmetry






2. A sigma bond and two pi bonds






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






4. Highest energy no separation. or 120 separation.






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






6. 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.






7. 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.






8. Hydrocarbon with one or more carbon carbon triple bond






9. Kmno4






10. 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






11. Alkenes oxidzed with kmno4 - if made with cold - dilue - make OH on each side of double bond - diols or glycol in syn orientation






12. Monosubstituted ethylene






13. When boat flips






14. If reagent has a bunch of oxygen






15. Name for propanal






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






17. Object that is not superimposable upon mirror image






18. Is bonded to only one other carbon atom






19. A = observed rotation / concentration * length






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






21. Transfer of electrions from one atome to another






22. Di - tri - t - sec - n -






23. F - CL - Br - I






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






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






26. Charged - need electrons






27. 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-






28. Two hydroxyl groups






29. Zn/h or CH3/s with ozonolysis






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






31. M - chloroperoxybenzoic acid






32. Name for ethanal






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






34. Rotations cancel each other out therefore no optical activity






35. More likely it is to attract positively charged proton. nucleophilic strength decreses: RO->HO>RCO2>ROH>H2O






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






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






38. Compounds with halogen






39. One s and two p 120 degree apart






40. Iso - neo - cyclo






41. Lowest priority group projects into the page






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






43. O3






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






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






46. Alphabetical order of alkane rxn






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






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






49. Carbon carbon triple bonds. Suffix-yne.






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