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. F - CL - Br - I






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






3. One s and two p 120 degree apart






4. 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






5. Carbon double bonded to an oxygen






6. What is produced when o3 with lialh4 or nabh4






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






8. 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.






9. Hydrocarbon with one or more carbon carbon triple bond






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






11. Carbon with four different substituents and lack a plane of symmetry






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






13. Zn/h or CH3/s with ozonolysis






14. Object that is not superimposable upon mirror image






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






16. A molecule with an internal plane of symmetry






17. Two hydroxyl groups






18. Name for propanal






19. Iso - neo - cyclo






20. When bond angles deviate from ideal values






21. 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.






22. Name for mathanal






23. Goal is to produce most stable carbocation


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






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






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






27. Sharing of electron between atoms






28. Kmno4






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






30. Compounds with halogen






31. Most favorable of staggared conformations






32. Carbon carbon triple bonds. Suffix-yne.






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






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


35. 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-






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






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






38. Rotations cancel each other out therefore no optical activity






39. Methyl are 60 degrees apart. kinda stable






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






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






42. Charged - need electrons






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






44. O3






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






46. Di - tri - t - sec - n -






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






48. In presence of peroxide - oxygen or ultraviolet light. antimarkonikov because they want a stable free radical. therefore X ends up on least subsituted carbon






49. If reagent has a bunch of oxygen






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