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






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






4. 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






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






6. Not solvated






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






8. Object that is not superimposable upon mirror image






9. Zn/h or CH3/s with ozonolysis






10. Common name for ethyne






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






12. M - chloroperoxybenzoic acid






13. Monosubstituted ethylene






14. 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






15. Most favorable of staggared conformations






16. 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






17. Highest energy no separation. or 120 separation.






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






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






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






21. Name for propanal






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






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






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






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






26. When boat flips






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






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






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






30. Name for ethanal






31. Two hydroxyl groups






32. Di - tri - t - sec - n -






33. If reagent has a bunch of oxygen






34. N - l - ml - ms






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






36. Alphabetical order of alkane rxn






37. Refers to the =CH2 group






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. Carbon carbon triple bonds. Suffix-yne.






40. Functionality is specified by alkoxy- prefix. ROR






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






42. When bond angles deviate from ideal values






43. Formed by mixing different types of orbitals






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






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






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


47. Compounds with halogen






48. Combustion reaction occurs through a radical process






49. O3






50. Goal is to produce most stable carbocation
