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. Sharing of electron between atoms






2. F - CL - Br - I






3. N - l - ml - ms






4. Zn/h or CH3/s with ozonolysis






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






6. Carbon double bonded to an oxygen






7. A sigma bond and two pi bonds






8. Common name for ethyne






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






10. Steps of free radical substitution






11. 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.






12. O3






13. Iso - neo - cyclo






14. Object that is not superimposable upon mirror image






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






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






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






18. Describes the exact spatial arrangement of groups of atoms independent of other molecules.






19. 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.






20. A molecule with an internal plane of symmetry






21. Is bonded to only one other carbon atom






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






23. Diol with hydroxyl group on same carbon






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






25. Methyl are 60 degrees apart. kinda stable






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






27. 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






28. Name for mathanal






29. Two hydroxyl groups






30. Kmno4






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






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






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

34. 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-






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






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






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






38. Compounds with halogen






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






40. What is produced when o3 with lialh4 or nabh4






41. When a molecular orbital is formed head to head or tail to tail. all single bonds are tehese.






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






43. Transfer of electrions from one atome to another






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






45. One s and two p 120 degree apart






46. Di - tri - t - sec - n -






47. Same molecular formula but different structure






48. Goal is to produce most stable carbocation

49. A = observed rotation / concentration * length






50. Most favorable of staggared conformations
