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. Transfer of electrions from one atome to another






2. Methyl are 60 degrees apart. kinda stable






3. Monosubstituted ethylene






4. Rotations cancel each other out therefore no optical activity






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






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






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






8. Sharing of electron between atoms






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






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






11. Steps of free radical substitution






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






13. If reagent has a bunch of oxygen






14. M - chloroperoxybenzoic acid






15. Goal is to produce most stable carbocation

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






17. What is produced when o3 with lialh4 or nabh4






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






19. Diols with hydroxyl group on adjacent carbon






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






21. Refers to the =CH2 group






22. Two hydroxyl groups






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






24. One s and two p 120 degree apart






25. Is bonded to only one other carbon atom






26. Lowest priority group projects into the page






27. Di - tri - t - sec - n -






28. 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






29. Diol with hydroxyl group on same carbon






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






31. Charged - need electrons






32. Hydrocarbon with one or more carbon carbon triple bond






33. 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.






34. N - l - ml - ms






35. Carbon carbon triple bonds. Suffix-yne.






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






37. Results when nonadjacent atoms or groups compete for space. dominant source of energy in flagpole interactions of the boat conformation. thus it goes in various conformations like chair boat and twist.






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






39. Formed by mixing different types of orbitals






40. When bond angles deviate from ideal values






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






42. A sigma bond and two pi bonds






43. Name for mathanal






44. What are the best leaving groups?






45. Not solvated






46. Compounds with halogen






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






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






49. Carbon double bonded to an oxygen






50. Combustion reaction occurs through a radical process
