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. 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-






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






3. Transfer of electrions from one atome to another






4. 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






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






6. Common name for ethyne






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






8. Most favorable of staggared conformations






9. Rotations cancel each other out therefore no optical activity






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






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






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






13. Compounds with halogen






14. Combustion reaction occurs through a radical process






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






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






17. Carbon double bonded to an oxygen






18. When boat flips






19. Sharing of electron between atoms






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






21. Highest energy no separation. or 120 separation.






22. Name for mathanal






23. A sigma bond and two pi bonds






24. Monosubstituted ethylene






25. Hydrocarbon with one or more carbon carbon triple bond






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






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






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






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






30. N - l - ml - ms






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






32. Kmno4






33. 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






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






35. Refers to the =CH2 group






36. When bond angles deviate from ideal values






37. Diols with hydroxyl group on adjacent carbon






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






39. Functionality is specified by alkoxy- prefix. ROR






40. 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






41. O3






42. One s and two p 120 degree apart






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






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






45. Carbon carbon triple bonds. Suffix-yne.






46. Charged - need electrons






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






48. 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.






49. Goal is to produce most stable carbocation

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
