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. Carbon double bonded to an oxygen






2. Carbon carbon triple bonds. Suffix-yne.






3. Is bonded to only one other carbon atom






4. Formed by mixing different types of orbitals






5. N - l - ml - ms






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






7. Common name for ethyne






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






9. Compounds with halogen






10. A molecule with an internal plane of symmetry






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






12. Sharing of electron between atoms






13. What are the best leaving groups?






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






15. Di - tri - t - sec - n -






16. Configuration in relation to another chiral molecule. use it to determine if a molecule is an enantiomer - diastereomer - etc






17. Transfer of electrions from one atome to another






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






19. Two hydroxyl groups






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






21. O3






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






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






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






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






26. One s and two p 120 degree apart






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






28. Name for propanal






29. Object that is not superimposable upon mirror image






30. Same molecular formula but different structure






31. Diol with hydroxyl group on same carbon






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






33. Highest energy no separation. or 120 separation.






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






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






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






37. Zn/h or CH3/s with ozonolysis






38. M - chloroperoxybenzoic acid






39. Refers to the =CH2 group






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






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






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






43. 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






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






45. Name for ethanal






46. Alphabetical order of alkane rxn






47. Hydrocarbon with one or more carbon carbon triple bond






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






49. Rotations cancel each other out therefore no optical activity






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