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. Arise from angle strain - torsional strian and nonbonded strain






2. Highest energy no separation. or 120 separation.






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






4. Refers to the =CH2 group






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






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






7. Zn/h or CH3/s with ozonolysis






8. 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.






9. Name for mathanal






10. What is produced when o3 with lialh4 or nabh4






11. Combustion reaction occurs through a radical process






12. Lowest priority group projects into the page






13. No double bonds. it has the maximum number of hydrogens.






14. A sigma bond and two pi bonds






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






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






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






18. Moleculse that have the opposite configuration at their one chiral center. or if multiple chiral centers - must have the opposite configuration at every one of their chiral centers to be enantiomers. identical physical properties and much of the same






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






20. N - l - ml - ms






21. Same molecular formula but different structure






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






23. Common name for ethyne






24. Hydrocarbon with one or more carbon carbon triple bond






25. When boat flips






26. A = observed rotation / concentration * length






27. Iso - neo - cyclo






28. One s and two p 120 degree apart






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






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






31. Kmno4






32. A molecule with an internal plane of symmetry






33. Carbon double bonded to an oxygen






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






35. Not solvated






36. Functionality is specified by alkoxy- prefix. ROR






37. Two hydroxyl groups






38. Steps of free radical substitution






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






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






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






42. Compounds with halogen






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






44. Carbon carbon triple bonds. Suffix-yne.






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






46. 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






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






48. Monosubstituted ethylene






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






50. What are the best leaving groups?
