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. 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






2. Name for mathanal






3. Charged - need electrons






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






5. What are the best leaving groups?






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






7. Methyl are 60 degrees apart. kinda stable






8. A molecule with an internal plane of symmetry






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






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






11. Carbon carbon triple bonds. Suffix-yne.






12. 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.






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






14. Is bonded to only one other carbon atom






15. Not solvated






16. Rotations cancel each other out therefore no optical activity






17. Formed by mixing different types of orbitals






18. A = observed rotation / concentration * length






19. Monosubstituted ethylene






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






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. Name for ethanal






23. Object that is not superimposable upon mirror image






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






25. Combustion reaction occurs through a radical process






26. If a compound is able to rotate plane polarized light.






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






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






29. F - CL - Br - I






30. Diol with hydroxyl group on same carbon






31. Functionality is specified by alkoxy- prefix. ROR






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






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






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






35. Alphabetical order of alkane rxn






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






37. A sigma bond and two pi bonds






38. Nitrogen containing compound - longest chain attached to nitrogen used in backbone. use e and replace with AMINE. if more complex molecule present - use prefix amino. IF additional group added - use N-






39. Diols with hydroxyl group on adjacent carbon






40. Refers to the =CH2 group






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






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






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






44. When boat flips






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






46. Common name for ethyne






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






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






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






50. Goal is to produce most stable carbocation
