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. What are the best leaving groups?






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






3. 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






4. Kmno4






5. M - chloroperoxybenzoic acid






6. 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-






7. Object that is not superimposable upon mirror image






8. When bond angles deviate from ideal values






9. One s and three p orbitals






10. Sharing of electron between atoms






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






12. A sigma bond and two pi bonds






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






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






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






16. Most favorable of staggared conformations






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






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






19. A = observed rotation / concentration * length






20. Hydrocarbon with one or more carbon carbon triple bond






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






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






23. Three different substitutents often have plane of symmetry. and rotation of 180 will allow molecule to be superimposed on mirror image






24. Functionality is specified by alkoxy- prefix. ROR






25. 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






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






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






28. Refers to the =CH2 group






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






30. Monosubstituted ethylene






31. Formed by mixing different types of orbitals






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






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






34. If reagent has a bunch of oxygen






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






36. Transfer of electrions from one atome to another






37. Carbon carbon triple bonds. Suffix-yne.






38. Goal is to produce most stable carbocation

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






40. N - l - ml - ms






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






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






43. O3






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






45. Combustion reaction occurs through a radical process






46. Charged - need electrons






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






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






49. One s and two p 120 degree apart






50. Name for ethanal
