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. Name for mathanal






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






3. Diol with hydroxyl group on same carbon






4. 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-






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






6. 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






7. Combustion reaction occurs through a radical process






8. Formed by mixing different types of orbitals






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






10. Monosubstituted ethylene






11. O3






12. What is produced when o3 with lialh4 or nabh4






13. One s and two p 120 degree apart






14. Refers to the =CH2 group






15. Rotations cancel each other out therefore no optical activity






16. Goal is to produce most stable carbocation

17. N - l - ml - ms






18. 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






19. Alkene oxidized with this - strong oxidizing agent. CH3CO3H or mcpba and it makes epoxide or oxirane






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






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






22. Not solvated






23. Lowest priority group projects into the page






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






25. Carbon carbon triple bonds. Suffix-yne.






26. Always receive number one. contain carbonyl and OH group - very oxidized. highest priority functional group.






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






28. 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






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






30. When bond angles deviate from ideal values






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






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






33. Compounds with halogen






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






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






36. A = observed rotation / concentration * length






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






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






39. Name for ethanal






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






41. Kmno4






42. Carbon double bonded to an oxygen






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






44. 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.






45. Is bonded to only one other carbon atom






46. Charged - need electrons






47. Nucleus lover. electron rich species that are attracked to charged atoms






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






49. Zn/h or CH3/s with ozonolysis






50. 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
