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. Most favorable of staggared conformations






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






3. O3






4. Carbon carbon triple bonds. Suffix-yne.






5. No double bonds. it has the maximum number of hydrogens.






6. One s and three p orbitals






7. Combustion reaction occurs through a radical process






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






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






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






11. 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-






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






13. Steps of free radical substitution






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






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






16. When boat flips






17. Refers to the =CH2 group






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






19. A molecule with an internal plane of symmetry






20. Iso - neo - cyclo






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






22. If reagent has a bunch of oxygen






23. Rotations cancel each other out therefore no optical activity






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






25. 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.






26. A sigma bond and two pi bonds






27. Transfer of electrions from one atome to another






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






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






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






31. Kmno4






32. M - chloroperoxybenzoic acid






33. Not solvated






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






35. Diols with hydroxyl group on adjacent carbon






36. One s and two p 120 degree apart






37. Name for propanal






38. A = observed rotation / concentration * length






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






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






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






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






43. What is produced when o3 with lialh4 or nabh4






44. Two hydroxyl groups






45. Goal is to produce most stable carbocation


46. Lowest priority group projects into the page






47. More likely it is to attract positively charged proton. nucleophilic strength decreses: RO->HO>RCO2>ROH>H2O






48. Name for mathanal






49. Functionality is specified by alkoxy- prefix. ROR






50. Common name for ethyne
