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. Functionality is specified by alkoxy- prefix. ROR






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






3. Zn/h or CH3/s with ozonolysis






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






5. A = observed rotation / concentration * length






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






7. Steps of free radical substitution






8. Configuration in relation to another chiral molecule. use it to determine if a molecule is an enantiomer - diastereomer - etc






9. Sharing of electron between atoms






10. Not solvated






11. Alphabetical order of alkane rxn






12. Nonsuperimposable mirror image of chiral objects - a specific steroisomer.






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






14. Highest energy no separation. or 120 separation.






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






16. A molecule with an internal plane of symmetry






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






18. Transfer of electrions from one atome to another






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






20. Iso - neo - cyclo






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






22. Carbon double bonded to an oxygen






23. If reagent has a bunch of oxygen






24. When two p orbitals line up in parallel and electron clouds overlap. it exsits over a single bond.






25. Formed by mixing different types of orbitals






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






27. Object that is not superimposable upon mirror image






28. When boat flips






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






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. Hydrocarbon with one or more carbon carbon triple bond






32. Carbon carbon triple bonds. Suffix-yne.






33. What are the best leaving groups?






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






35. 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






36. One s and two p 120 degree apart






37. Name for mathanal






38. One s and three p orbitals






39. Goal is to produce most stable carbocation


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






41. Charged - need electrons






42. Rotations cancel each other out therefore no optical activity






43. 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






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






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






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






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






48. Lowest priority group projects into the page






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






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