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. Electrons of pi bond are reactive and easily attacked by molecules that want e pair e.g. electrophiles.






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






3. 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






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






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






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






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






8. Functionality is specified by alkoxy- prefix. ROR






9. Sharing of electron between atoms






10. Most favorable of staggared conformations






11. Name for propanal






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






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






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






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






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






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






18. Kmno4






19. Is bonded to only one other carbon atom






20. Rotations cancel each other out therefore no optical activity






21. Carbon double bonded to an oxygen






22. If reagent has a bunch of oxygen






23. Methyl are 60 degrees apart. kinda stable






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






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






26. One s and three p orbitals






27. Transfer of electrions from one atome to another






28. Combustion reaction occurs through a radical process






29. 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






30. Di - tri - t - sec - n -






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






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






33. 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






34. O3






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






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






37. Name for ethanal






38. Goal is to produce most stable carbocation


39. F - CL - Br - I






40. Carbon carbon triple bonds. Suffix-yne.






41. Describes the exact spatial arrangement of groups of atoms independent of other molecules.






42. Diol with hydroxyl group on same carbon






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






44. When boat flips






45. A molecule with an internal plane of symmetry






46. M - chloroperoxybenzoic acid






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






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






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


50. Same molecular formula but different structure
