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. Name for ethanal






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






3. Goal is to produce most stable carbocation

4. Object that is not superimposable upon mirror image






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






6. 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






7. Same molecular formula but different structure






8. Hydrocarbon with one or more carbon carbon triple bond






9. Zn/h or CH3/s with ozonolysis






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






11. Iso - neo - cyclo






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






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






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






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






16. Lowest priority group projects into the page






17. Refers to the =CH2 group






18. M - chloroperoxybenzoic acid






19. Combustion reaction occurs through a radical process






20. 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






21. Two hydroxyl groups






22. Diol with hydroxyl group on same carbon






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






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






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






26. Charged - need electrons






27. Sharing of electron between atoms






28. Carbon double bonded to an oxygen






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






30. When bond angles deviate from ideal values






31. One s and three p orbitals






32. 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.






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






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






35. Highest energy no separation. or 120 separation.






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






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






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






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






40. Diols with hydroxyl group on adjacent carbon






41. Most favorable of staggared conformations






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






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






44. Alphabetical order of alkane rxn






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






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






47. Carbon carbon triple bonds. Suffix-yne.






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






49. A sigma bond and two pi bonds






50. 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
