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. Lowest priority group projects into the page






3. 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






4. Steps of free radical substitution






5. Zn/h or CH3/s with ozonolysis






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






7. Diol with hydroxyl group on same carbon






8. Two p orbital form pi and third p orbital combine with s to make two sp hybrid. 180 degree apart






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






10. Object that is not superimposable upon mirror image






11. Name for ethanal






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






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






14. Highest energy no separation. or 120 separation.






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






16. Alphabetical order of alkane rxn






17. One s and two p 120 degree apart






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






19. Formed by mixing different types of orbitals






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






21. Palladium or barium sulfate (BaSO4) with quinoline. occur on metal surface - make cis.

22. Methyl are 60 degrees apart. kinda stable






23. Same molecular formula but different structure






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






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






26. Combustion reaction occurs through a radical process






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






28. 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






29. Hydrocarbon with one or more carbon carbon triple bond






30. 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






31. Diols with hydroxyl group on adjacent carbon






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






33. Not solvated






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






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






36. Carbon carbon triple bonds. Suffix-yne.






37. What is produced when o3 with lialh4 or nabh4






38. 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.






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






40. Creation of long - high molecular weight polymer composed of repeating subunit called monomers. occur through a radical mechanism.






41. When boat flips






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






43. Monosubstituted ethylene






44. Is bonded to only one other carbon atom






45. A sigma bond and two pi bonds






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






47. A molecule with an internal plane of symmetry






48. Common name for ethyne






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






50. Goal is to produce most stable carbocation
