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. Is bonded to only one other carbon atom






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






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






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






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






6. 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.






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






8. Object that is not superimposable upon mirror image






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






10. F - CL - Br - I






11. M - chloroperoxybenzoic acid






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






13. 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






14. Name for mathanal






15. Steps of free radical substitution






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






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






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






19. One s and two p 120 degree apart






20. One s and three p orbitals






21. Two hydroxyl groups






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






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






24. Highest energy no separation. or 120 separation.






25. Same chemical formula. same atomic connectivity . different in how atoms are arranged in space






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






27. Sharing of electron between atoms






28. A = observed rotation / concentration * length






29. 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.






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






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






32. A molecule with an internal plane of symmetry






33. 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.






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






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






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






37. Monosubstituted ethylene






38. When boat flips






39. Iso - neo - cyclo






40. What is produced when o3 with lialh4 or nabh4






41. Two p orbital form pi and third p orbital combine with s to make two sp hybrid. 180 degree apart






42. O3






43. Rotations cancel each other out therefore no optical activity






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






45. Lowest priority group projects into the page






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






47. Compounds with halogen






48. Goal is to produce most stable carbocation

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






50. Kmno4
