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. What are the best leaving groups?






3. Solvents with protons in solution - e.g. water or alcohol. large atoms tend to be better nucleophiles in here because they can shed the solvating protons around them and are more polarizable






4. O3






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






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






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






8. Is bonded to only one other carbon atom






9. Compounds with halogen






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






11. Iso - neo - cyclo






12. One s and three p orbitals






13. Two hydroxyl groups






14. Di - tri - t - sec - n -






15. 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






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






17. Kmno4






18. Common name for ethyne






19. When bond angles deviate from ideal values






20. Monosubstituted ethylene






21. A sigma bond and two pi bonds






22. Combustion reaction occurs through a radical process






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






24. Name for mathanal






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






26. 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.






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






28. 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.






29. Rotations cancel each other out therefore no optical activity






30. Name for ethanal






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






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






33. When boat flips






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






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






36. Zn/h or CH3/s with ozonolysis






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






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. 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






40. M - chloroperoxybenzoic acid






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






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






43. Diols with hydroxyl group on adjacent carbon






44. 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






45. Highest energy no separation. or 120 separation.






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






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






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






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






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