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






2. Not solvated






3. Is bonded to only one other carbon atom






4. Goal is to produce most stable carbocation


5. Functionality is specified by alkoxy- prefix. ROR






6. Monosubstituted ethylene






7. Carbon carbon triple bonds. Suffix-yne.






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






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






10. M - chloroperoxybenzoic acid






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






12. Di - tri - t - sec - n -






13. O3






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






15. 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.






16. Rotations cancel each other out therefore no optical activity






17. One s and three p orbitals






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






19. Diols with hydroxyl group on adjacent carbon






20. Combustion reaction occurs through a radical process






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






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






23. Kmno4






24. Carbon double bonded to an oxygen






25. Lowest priority group projects into the page






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. What is produced when o3 with lialh4 or nabh4






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






29. Diol with hydroxyl group on same carbon






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






31. Iso - neo - cyclo






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






33. If reagent has a bunch of oxygen






34. 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






35. Palladium or barium sulfate (BaSO4) with quinoline. occur on metal surface - make cis.


36. When bond angles deviate from ideal values






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






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






39. 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-






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






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






42. One s and two p 120 degree apart






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






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






45. Highest energy no separation. or 120 separation.






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






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






48. 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






49. A molecule with an internal plane of symmetry






50. Formed by mixing different types of orbitals
