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






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






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






4. Compounds with halogen






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






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






7. 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






8. 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






9. Carbon double bonded to an oxygen






10. Diols with hydroxyl group on adjacent carbon






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






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






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






14. Refers to the =CH2 group






15. Goal is to produce most stable carbocation

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






17. F - CL - Br - I






18. Name for mathanal






19. Formed by mixing different types of orbitals






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






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






22. If reagent has a bunch of oxygen






23. Arise from angle strain - torsional strian and nonbonded strain






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






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






26. Kmno4






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






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






29. Diol with hydroxyl group on same carbon






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






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






32. Highest energy no separation. or 120 separation.






33. When bond angles deviate from ideal values






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






35. A molecule with an internal plane of symmetry






36. Sharing of electron between atoms






37. Di - tri - t - sec - n -






38. One s and two p 120 degree apart






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






40. What are the best leaving groups?






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






42. Reducing an alkene by adding molecular hydrogen to double bond with aid of metal catalyst. e.g. pt - pd - ni. takes place on surface of metal so it does syn addition






43. N - l - ml - ms






44. Transfer of electrions from one atome to another






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






46. Common name for ethyne






47. Charged - need electrons






48. Iso - neo - cyclo






49. Alphabetical order of alkane rxn






50. M - chloroperoxybenzoic acid
