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. What is produced when o3 with lialh4 or nabh4






2. Sharing of electron between atoms






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






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






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






6. Formed by mixing different types of orbitals






7. Lowest priority group projects into the page






8. One s and two p 120 degree apart






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






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






11. Name for ethanal






12. 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-






13. Object that is not superimposable upon mirror image






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






15. Refers to the =CH2 group






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






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






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






19. Carbon carbon triple bonds. Suffix-yne.






20. When boat flips






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






22. 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.






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






24. Hydrocarbon with one or more carbon carbon triple bond






25. F - CL - Br - I






26. Methyl are 60 degrees apart. kinda stable






27. Carbon double bonded to an oxygen






28. If reagent has a bunch of oxygen






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






30. Most favorable of staggared conformations






31. Diols with hydroxyl group on adjacent carbon






32. Not solvated






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






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






35. Rotations cancel each other out therefore no optical activity






36. 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.






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






38. Highest energy no separation. or 120 separation.






39. Two p orbital form pi and third p orbital combine with s to make two sp hybrid. 180 degree apart






40. N - l - ml - ms






41. Alphabetical order of alkane rxn






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






43. Monosubstituted ethylene






44. Charged - need electrons






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






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






47. Common name for ethyne






48. 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






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






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