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






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






3. M - chloroperoxybenzoic acid






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






5. Carbon carbon triple bonds. Suffix-yne.






6. Carbon double bonded to an oxygen






7. Functionality is specified by alkoxy- prefix. ROR






8. A sigma bond and two pi bonds






9. A molecule with an internal plane of symmetry






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






11. N - l - ml - ms






12. Two hydroxyl groups






13. Same molecular formula but different structure






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






15. Common name for ethyne






16. When boat flips






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






18. O3






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






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






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






22. Di - tri - t - sec - n -






23. Diols with hydroxyl group on adjacent carbon






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






25. Sharing of electron between atoms






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






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






28. Refers to the =CH2 group






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






30. Highest energy no separation. or 120 separation.






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






32. Charged - need electrons






33. One s and three p orbitals






34. 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-






35. One s and two p 120 degree apart






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






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






38. Alphabetical order of alkane rxn






39. 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.






40. Combustion reaction occurs through a radical process






41. A = observed rotation / concentration * length






42. 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






43. What are the best leaving groups?






44. Monosubstituted ethylene






45. Name for ethanal






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






47. Is bonded to only one other carbon atom






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






49. What is produced when o3 with lialh4 or nabh4






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