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






2. Diols with hydroxyl group on adjacent carbon






3. When boat flips






4. Carbon double bonded to an oxygen






5. Compounds with halogen






6. Combustion reaction occurs through a radical process






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






8. Two hydroxyl groups






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






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






11. Name for ethanal






12. Hydrocarbon with one or more carbon carbon triple bond






13. 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-






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






16. What are the best leaving groups?






17. Most favorable of staggared conformations






18. N - l - ml - ms






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






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






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






22. Same molecular formula but different structure






23. Steps of free radical substitution






24. Object that is not superimposable upon mirror image






25. Transfer of electrions from one atome to another






26. Highest energy no separation. or 120 separation.






27. If reagent has a bunch of oxygen






28. Di - tri - t - sec - n -






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






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






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






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






35. Formed by mixing different types of orbitals






36. Functionality is specified by alkoxy- prefix. ROR






37. 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






38. Methyl are 60 degrees apart. kinda stable






39. Rotations cancel each other out therefore no optical activity






40. Name for propanal






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






42. 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.






43. Common name for ethyne






44. F - CL - Br - I






45. Lowest priority group projects into the page






46. What is produced when o3 with lialh4 or nabh4






47. In which one or morehydrogen atoms are replaced with a halogen atom. via free radical substitution






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






49. A radical transfers a hydrogen atom to another radical and makes an alkane and alkene






50. Results when cyclic molecules must assume conformations that have eclipsed interactions
