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. A = observed rotation / concentration * length






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






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






4. Sharing of electron between atoms






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






6. Charged - need electrons






7. Iso - neo - cyclo






8. What is produced when o3 with lialh4 or nabh4






9. Methyl are 60 degrees apart. kinda stable






10. F - CL - Br - I






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






12. One s and three p orbitals






13. Is bonded to only one other carbon atom






14. Same molecular formula but different structure






15. Diol with hydroxyl group on same carbon






16. Zn/h or CH3/s with ozonolysis






17. 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






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






19. Carbon carbon triple bonds. Suffix-yne.






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






21. A molecule with an internal plane of symmetry






22. Combustion reaction occurs through a radical process






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






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






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






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






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






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






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






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






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






32. Formed by mixing different types of orbitals






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






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






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






36. Most favorable of staggared conformations






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. Di - tri - t - sec - n -






39. Carbon double bonded to an oxygen






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






41. Common name for ethyne






42. 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.






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






44. Kmno4






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






46. Compounds with halogen






47. Two hydroxyl groups






48. Monosubstituted ethylene






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






50. Name for mathanal
