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. One s and three p orbitals






2. Functionality is specified by alkoxy- prefix. ROR






3. Methyl are 60 degrees apart. kinda stable






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






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






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






7. Kmno4






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






9. Goal is to produce most stable carbocation

10. One s and two p 120 degree apart






11. Object that is not superimposable upon mirror image






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






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






14. Monosubstituted ethylene






15. Same molecular formula but different structure






16. A molecule with an internal plane of symmetry






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






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






19. Sharing of electron between atoms






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






21. Transfer of electrions from one atome to another






22. Formed by mixing different types of orbitals






23. Two hydroxyl groups






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

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






26. 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






27. O3






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






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






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. Name for propanal






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






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






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






35. Rotations cancel each other out therefore no optical activity






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






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






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






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






40. Combustion reaction occurs through a radical process






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






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






43. A sigma bond and two pi bonds






44. Carbon carbon triple bonds. Suffix-yne.






45. Steps of free radical substitution






46. Highest energy no separation. or 120 separation.






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






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






49. Name for mathanal






50. A = observed rotation / concentration * length
