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. Sharing of electron between atoms






2. Most favorable of staggared conformations






3. Rotations cancel each other out therefore no optical activity






4. Combustion reaction occurs through a radical process






5. Carbon carbon triple bonds. Suffix-yne.






6. Transfer of electrions from one atome to another






7. Highest energy no separation. or 120 separation.






8. Object that is not superimposable upon mirror image






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






10. Name for propanal






11. When boat flips






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






13. A = observed rotation / concentration * length






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






15. Hydrocarbon with one or more carbon carbon triple bond






16. Kmno4






17. Alphabetical order of alkane rxn






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






19. M - chloroperoxybenzoic acid






20. Carbon double bonded to an oxygen






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






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






23. When bond angles deviate from ideal values






24. Configuration in relation to another chiral molecule. use it to determine if a molecule is an enantiomer - diastereomer - etc






25. Refers to the =CH2 group






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






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






28. Goal is to produce most stable carbocation

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






30. 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-






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






32. Charged - need electrons






33. One s and two p 120 degree apart






34. One s and three p orbitals






35. Name for ethanal






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






37. Is bonded to only one other carbon atom






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






39. A molecule with an internal plane of symmetry






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






41. Iso - neo - cyclo






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






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






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






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

46. Describes the exact spatial arrangement of groups of atoms independent of other molecules.






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






48. Not solvated






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. What is produced when o3 with lialh4 or nabh4
