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. 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.






2. Transfer of electrions from one atome to another






3. Combustion reaction occurs through a radical process






4. Hydrocarbon with one or more carbon carbon triple bond






5. A sigma bond and two pi bonds






6. 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






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






8. Sharing of electron between atoms






9. Most favorable of staggared conformations






10. O3






11. Monosubstituted ethylene






12. Object that is not superimposable upon mirror image






13. Name for propanal






14. One s and two p 120 degree apart






15. Compounds with halogen






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






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

18. Not solvated






19. What are the best leaving groups?






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






21. Solvents with protons in solution - e.g. water or alcohol. large atoms tend to be better nucleophiles in here because they can shed the solvating protons around them and are more polarizable






22. 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






23. Rotations cancel each other out therefore no optical activity






24. N - l - ml - ms






25. A = observed rotation / concentration * length






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






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






28. Methyl are 60 degrees apart. kinda stable






29. A molecule with an internal plane of symmetry






30. 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.






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






32. When boat flips






33. Highest energy no separation. or 120 separation.






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






35. Formed by mixing different types of orbitals






36. Carbon double bonded to an oxygen






37. Two hydroxyl groups






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






39. Kmno4






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






41. Is bonded to only one other carbon atom






42. Carbon carbon triple bonds. Suffix-yne.






43. 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






44. Common name for ethyne






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






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






47. Functionality is specified by alkoxy- prefix. ROR






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






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






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