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. Compounds with halogen






2. N - l - ml - ms






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






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






5. Lowest priority group projects into the page






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






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






8. A molecule with an internal plane of symmetry






9. Is bonded to only one other carbon atom






10. Carbon carbon triple bonds. Suffix-yne.






11. Functionality is specified by alkoxy- prefix. ROR






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






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






14. Same molecular formula but different structure






15. 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






16. Sharing of electron between atoms






17. Monosubstituted ethylene






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






19. Methyl are 60 degrees apart. kinda stable






20. What is produced when o3 with lialh4 or nabh4






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






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






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






24. A sigma bond and two pi bonds






25. Carbon double bonded to an oxygen






26. O3






27. If reagent has a bunch of oxygen






28. Formed by mixing different types of orbitals






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






30. When boat flips






31. Iso - neo - cyclo






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






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






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






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






36. Combustion reaction occurs through a radical process






37. What are the best leaving groups?






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






39. Kmno4






40. Rotations cancel each other out therefore no optical activity






41. Object that is not superimposable upon mirror image






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






43. Goal is to produce most stable carbocation

44. Alphabetical order of alkane rxn






45. Most favorable of staggared conformations






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






47. Name for mathanal






48. One s and two p 120 degree apart






49. 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






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