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. Common name for ethyne






3. When bond angles deviate from ideal values






4. Diol with hydroxyl group on same carbon






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






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






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






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






9. 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






10. Carbon carbon triple bonds. Suffix-yne.






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






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. Sharing of electron between atoms






14. One s and two p 120 degree apart






15. A = observed rotation / concentration * length






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






17. Di - tri - t - sec - n -






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






19. Name for ethanal






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






21. Object that is not superimposable upon mirror image






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






23. Two hydroxyl groups






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






25. Iso - neo - cyclo






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






27. Lowest priority group projects into the page






28. Name for mathanal






29. Diols with hydroxyl group on adjacent carbon






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. Same chemical formula. same atomic connectivity . different in how atoms are arranged in space






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






33. M - chloroperoxybenzoic acid






34. 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.






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






36. 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






37. Combustion reaction occurs through a radical process






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






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






40. Zn/h or CH3/s with ozonolysis






41. Refers to the =CH2 group






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






43. A molecule with an internal plane of symmetry






44. Water can be added to alkenes under acidic conditions. make carbocation. ends with alcohol






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






46. 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






47. 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






48. Alphabetical order of alkane rxn






49. Monosubstituted ethylene






50. O3
