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






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






3. 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.






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






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






6. Carbon double bonded to an oxygen






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






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






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






10. Refers to the =CH2 group






11. A = observed rotation / concentration * length






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






13. Name for propanal






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






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






16. Steps of free radical substitution






17. If reagent has a bunch of oxygen






18. F - CL - Br - I






19. Carbon with four different substituents and lack a plane of symmetry






20. Is bonded to only one other carbon atom






21. 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-






22. Carbon carbon triple bonds. Suffix-yne.






23. Diol with hydroxyl group on same carbon






24. Monosubstituted ethylene






25. Highest energy no separation. or 120 separation.






26. M - chloroperoxybenzoic acid






27. N - l - ml - ms






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






29. Formed by mixing different types of orbitals






30. Lowest priority group projects into the page






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






32. Charged - need electrons






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






34. 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






35. 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






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






37. What is produced when o3 with lialh4 or nabh4






38. Diols with hydroxyl group on adjacent carbon






39. Goal is to produce most stable carbocation

40. A molecule with an internal plane of symmetry






41. 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






42. Methyl are 60 degrees apart. kinda stable






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






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

45. Object that is not superimposable upon mirror image






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






47. Alkene oxidized with this - strong oxidizing agent. CH3CO3H or mcpba and it makes epoxide or oxirane






48. Zn/h or CH3/s with ozonolysis






49. Alphabetical order of alkane rxn






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