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






2. One s and two p 120 degree apart






3. A sigma bond and two pi bonds






4. 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






5. 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-






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






7. Highest energy no separation. or 120 separation.






8. One s and three p orbitals






9. Object that is not superimposable upon mirror image






10. Same molecular formula but different structure






11. 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






12. Common name for ethyne






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






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






15. Not solvated






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






17. Most favorable of staggared conformations






18. O3






19. Alphabetical order of alkane rxn






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






21. N - l - ml - ms






22. Iso - neo - cyclo






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






24. If reagent has a bunch of oxygen






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






26. Hydrocarbon with one or more carbon carbon triple bond






27. Differ in position of substitutents attached to a double bond or cycloalkane. Cis or trans or e or z






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






29. Name for mathanal






30. Carbon carbon triple bonds. Suffix-yne.






31. Carbon double bonded to an oxygen






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






33. Rotations cancel each other out therefore no optical activity






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






35. What are the best leaving groups?






36. Two hydroxyl groups






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






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






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






40. Is bonded to only one other carbon atom






41. Most similar. same molecule only at different points in their rotation. show them with newmans projections






42. What is produced when o3 with lialh4 or nabh4






43. Monosubstituted ethylene






44. Sharing of electron between atoms






45. Formed by mixing different types of orbitals






46. Functionality is specified by alkoxy- prefix. ROR






47. Share molecular formula but have different chemical and physical properties






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






49. Zn/h or CH3/s with ozonolysis






50. Lowest priority group projects into the page
