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






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






3. Carbon carbon triple bonds. Suffix-yne.






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






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






6. Same molecular formula but different structure






7. Most favorable of staggared conformations






8. O3






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






10. Lowest priority group projects into the page






11. Diols with hydroxyl group on adjacent carbon






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






13. What is produced when o3 with lialh4 or nabh4






14. 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






15. F - CL - Br - I






16. Monosubstituted ethylene






17. Name for mathanal






18. Charged - need electrons






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






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






21. Steps of free radical substitution






22. Formed by mixing different types of orbitals






23. 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.






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






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






26. Is bonded to only one other carbon atom






27. A sigma bond and two pi bonds






28. One s and three p orbitals






29. Rotations cancel each other out therefore no optical activity






30. Refers to the =CH2 group






31. Nitrogen containing compound - longest chain attached to nitrogen used in backbone. use e and replace with AMINE. if more complex molecule present - use prefix amino. IF additional group added - use N-






32. Compounds with halogen






33. Not solvated






34. 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






35. Di - tri - t - sec - n -






36. 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






37. Highest energy no separation. or 120 separation.






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






39. Name for propanal






40. Two hydroxyl groups






41. Functionality is specified by alkoxy- prefix. ROR






42. Methyl are 60 degrees apart. kinda stable






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






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






45. When boat flips






46. 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.






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






48. If reagent has a bunch of oxygen






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






50. When bond angles deviate from ideal values
