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. Di - tri - t - sec - n -






2. 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.






3. Name for ethanal






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






5. Formed by mixing different types of orbitals






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






7. What are the best leaving groups?






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






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






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






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






12. Highest energy no separation. or 120 separation.






13. Goal is to produce most stable carbocation

14. Occur when a molecule is broken down by heat. used to reduce the avverage molecular weight of heavy oils. c - c - bonds are cleave dand make small chain alkyl radicals that recombine to form different alkanes






15. Is bonded to only one other carbon atom






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






17. Zn/h or CH3/s with ozonolysis






18. When bond angles deviate from ideal values






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






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






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






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






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






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






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






26. F - CL - Br - I






27. Charged - need electrons






28. A = observed rotation / concentration * length






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






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






31. Moleculse that have the opposite configuration at their one chiral center. or if multiple chiral centers - must have the opposite configuration at every one of their chiral centers to be enantiomers. identical physical properties and much of the same






32. Two hydroxyl groups






33. Rotations cancel each other out therefore no optical activity






34. Palladium or barium sulfate (BaSO4) with quinoline. occur on metal surface - make cis.

35. Name for mathanal






36. 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






37. A sigma bond and two pi bonds






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






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






40. Iso - neo - cyclo






41. Most favorable of staggared conformations






42. Not solvated






43. When boat flips






44. 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-






45. Methyl are 60 degrees apart. kinda stable






46. Common name for ethyne






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






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






49. Functionality is specified by alkoxy- prefix. ROR






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