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






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






3. Highest energy no separation. or 120 separation.






4. 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






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






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






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






8. Is bonded to only one other carbon atom






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






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






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






12. Two hydroxyl groups






13. Nonterminal alkenes are cleaved to form two molar equivalent of carvoxylic acid ..make keton






14. F - CL - Br - I






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






16. Charged - need electrons






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






18. Methyl are 60 degrees apart. kinda stable






19. Object that is not superimposable upon mirror image






20. 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.






21. 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.






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






23. Diols with hydroxyl group on adjacent carbon






24. N - l - ml - ms






25. A molecule with an internal plane of symmetry






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






27. Kmno4






28. Sharing of electron between atoms






29. 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.






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






31. Steps of free radical substitution






32. A sigma bond and two pi bonds






33. Monosubstituted ethylene






34. Name for propanal






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






36. Formed by mixing different types of orbitals






37. Zn/h or CH3/s with ozonolysis






38. What is produced when o3 with lialh4 or nabh4






39. Name for ethanal






40. Carbon carbon triple bonds. Suffix-yne.






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






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






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






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






45. Lowest priority group projects into the page






46. One s and two p 120 degree apart






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






48. Goal is to produce most stable carbocation

49. Hydrocarbon with one or more carbon carbon triple bond






50. Diol with hydroxyl group on same carbon
