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. Goal is to produce most stable carbocation

3. What are the best leaving groups?






4. When boat flips






5. Object that is not superimposable upon mirror image






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






7. Lowest priority group projects into the page






8. Highest energy no separation. or 120 separation.






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

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






11. N - l - ml - ms






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






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






14. Iso - neo - cyclo






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






16. 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






17. O3






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






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






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






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






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






23. Compounds with halogen






24. Alphabetical order of alkane rxn






25. If reagent has a bunch of oxygen






26. Name for propanal






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






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






29. Di - tri - t - sec - n -






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






31. Diols with hydroxyl group on adjacent carbon






32. Charged - need electrons






33. One s and two p 120 degree apart






34. 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






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






36. Rotations cancel each other out therefore no optical activity






37. Methyl are 60 degrees apart. kinda stable






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






39. A molecule with an internal plane of symmetry






40. Common name for ethyne






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






42. What is produced when o3 with lialh4 or nabh4






43. Formed by mixing different types of orbitals






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






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






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






47. Functionality is specified by alkoxy- prefix. ROR






48. Zn/h or CH3/s with ozonolysis






49. Diol with hydroxyl group on same carbon






50. A sigma bond and two pi bonds
