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






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






3. F - CL - Br - I






4. Two hydroxyl groups






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






6. Carbon double bonded to an oxygen






7. Compounds with halogen






8. Most favorable of staggared conformations






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






10. Sharing of electron between atoms






11. When bond angles deviate from ideal values






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






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






14. What are the best leaving groups?






15. Alphabetical order of alkane rxn






16. Name for mathanal






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






18. Diols with hydroxyl group on adjacent carbon






19. 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-






20. One s and two p 120 degree apart






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






22. Kmno4






23. Same molecular formula but different structure






24. Combustion reaction occurs through a radical process






25. A sigma bond and two pi bonds






26. Formed by mixing different types of orbitals






27. Di - tri - t - sec - n -






28. Functionality is specified by alkoxy- prefix. ROR






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






30. Rotations cancel each other out therefore no optical activity






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






32. Configuration in relation to another chiral molecule. use it to determine if a molecule is an enantiomer - diastereomer - etc






33. A molecule with an internal plane of symmetry






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






35. Transfer of electrions from one atome to another






36. 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






37. Highest energy no separation. or 120 separation.






38. What is produced when o3 with lialh4 or nabh4






39. O3






40. Is bonded to only one other carbon atom






41. If reagent has a bunch of oxygen






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






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






44. Goal is to produce most stable carbocation

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






46. 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.






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






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






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






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