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






2. M - chloroperoxybenzoic acid






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






4. O3






5. 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






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






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






8. Highest energy no separation. or 120 separation.






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






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






11. When boat flips






12. N - l - ml - ms






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






14. Name for mathanal






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






16. Name for ethanal






17. Fast process. double bond is nucleophile and attack x2. make cyclic halonium ion with either br or cl. and make dihalo trans






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






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






20. Diol with hydroxyl group on same carbon






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






22. 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






23. Carbon carbon triple bonds. Suffix-yne.






24. 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.






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






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






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






28. A sigma bond and two pi bonds






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






30. F - CL - Br - I






31. Hydrocarbon with one or more carbon carbon triple bond






32. 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






33. Object that is not superimposable upon mirror image






34. Most favorable of staggared conformations






35. Lowest priority group projects into the page






36. Same molecular formula but different structure






37. Charged - need electrons






38. 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






39. Name for propanal






40. 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-






41. Methyl are 60 degrees apart. kinda stable






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






43. Functionality is specified by alkoxy- prefix. ROR






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






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






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






47. Compounds with halogen






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






49. A molecule with an internal plane of symmetry






50. One s and three p orbitals
