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






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






3. If reagent has a bunch of oxygen






4. One s and two p 120 degree apart






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






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






7. Not solvated






8. Diol with hydroxyl group on same carbon






9. M - chloroperoxybenzoic acid






10. Lowest priority group projects into the page






11. Common name for ethyne






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






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






14. Rotations cancel each other out therefore no optical activity






15. Name for propanal






16. A molecule with an internal plane of symmetry






17. Goal is to produce most stable carbocation

18. When boat flips






19. Formed by mixing different types of orbitals






20. Name for mathanal






21. Steps of free radical substitution






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






23. Is bonded to only one other carbon atom






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






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






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






27. 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-






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






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






30. F - CL - Br - I






31. Zn/h or CH3/s with ozonolysis






32. 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.






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






34. Di - tri - t - sec - n -






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






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






37. What are the best leaving groups?






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






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






40. Carbon double bonded to an oxygen






41. 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.






42. Carbon carbon triple bonds. Suffix-yne.






43. N - l - ml - ms






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






45. Monosubstituted ethylene






46. Share molecular formula but have different chemical and physical properties






47. 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






48. Same molecular formula but different structure






49. Three different substitutents often have plane of symmetry. and rotation of 180 will allow molecule to be superimposed on mirror image






50. Fast process. double bond is nucleophile and attack x2. make cyclic halonium ion with either br or cl. and make dihalo trans
