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. Two hydroxyl groups






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






3. Is bonded to only one other carbon atom






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






5. Alphabetical order of alkane rxn






6. Compounds with halogen






7. Name for propanal






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






9. Transfer of electrions from one atome to another






10. O3






11. 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






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






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






14. Formed by mixing different types of orbitals






15. Name for mathanal






16. Y = position of double bond - x is position of triple bond - root is the prefix representing the length of the principal carbon chain






17. Diols with hydroxyl group on adjacent carbon






18. A = observed rotation / concentration * length






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






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






21. Hydrocarbon with one or more carbon carbon triple bond






22. Most favorable of staggared conformations






23. Goal is to produce most stable carbocation


24. 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






25. Same molecular formula but different structure






26. 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.






27. Di - tri - t - sec - n -






28. Common name for ethyne






29. A sigma bond and two pi bonds






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






31. Sharing of electron between atoms






32. M - chloroperoxybenzoic acid






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






34. N - l - ml - ms






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






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. Combustion reaction occurs through a radical process






38. Rotations cancel each other out therefore no optical activity






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






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






41. 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






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






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






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






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






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






47. Methyl are 60 degrees apart. kinda stable






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






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






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