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. Diols with hydroxyl group on adjacent carbon






2. One s and two p 120 degree apart






3. What is produced when o3 with lialh4 or nabh4






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






6. Goal is to produce most stable carbocation

7. Non mirror image of configurational isomers. cis and trans alkenes are them. possible when a molecule has two or more stereogenic centers that differ at some but not alll of the centers. they require multiple chiral centers.






8. Transfer of electrions from one atome to another






9. Di - tri - t - sec - n -






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






11. Share molecular formula but have different chemical and physical properties






12. Steps of free radical substitution






13. Most favorable of staggared conformations






14. Highest energy no separation. or 120 separation.






15. Two hydroxyl groups






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






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






18. Lowest priority group projects into the page






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






20. Object that is not superimposable upon mirror image






21. Combustion reaction occurs through a radical process






22. O3






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






24. Monosubstituted ethylene






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






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






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






29. Name for mathanal






30. 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.






31. When boat flips






32. Kmno4






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






34. What are the best leaving groups?






35. A molecule with an internal plane of symmetry






36. Hydrocarbon with one or more carbon carbon triple bond






37. Iso - neo - cyclo






38. M - chloroperoxybenzoic acid






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






40. 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-






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






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






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






44. 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.






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






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






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






48. 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






49. Alphabetical order of alkane rxn






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