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. Rotations cancel each other out therefore no optical activity






2. 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-






3. Carbon carbon triple bonds. Suffix-yne.






4. F - CL - Br - I






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






6. Functionality is specified by alkoxy- prefix. ROR






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






8. Compounds with halogen






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






10. Name for propanal






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






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






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






14. A molecule with an internal plane of symmetry






15. Monosubstituted ethylene






16. 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.






17. 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






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






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






20. One s and two p 120 degree apart






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






22. Lowest priority group projects into the page






23. Iso - neo - cyclo






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






25. Name for mathanal






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






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






28. Goal is to produce most stable carbocation

29. Kmno4






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






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






32. N - l - ml - ms






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






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






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






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






37. Hydrocarbon with one or more carbon carbon triple bond






38. When boat flips






39. One s and three p orbitals






40. When bond angles deviate from ideal values






41. Transfer of electrions from one atome to another






42. Methyl are 60 degrees apart. kinda stable






43. Common name for ethyne






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






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






46. 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.






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






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






49. Highest energy no separation. or 120 separation.






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