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. What are the best leaving groups?






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






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






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






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






6. One s and three p orbitals






7. O3






8. 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






9. Same molecular formula but different structure






10. Name for mathanal






11. Diols with hydroxyl group on adjacent carbon






12. 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






13. Monosubstituted ethylene






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






15. Charged - need electrons






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






17. Object that is not superimposable upon mirror image






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






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






20. 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






21. 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-






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






23. N - l - ml - ms






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






25. Iso - neo - cyclo






26. Most favorable of staggared conformations






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






28. Name for propanal






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






30. Two hydroxyl groups






31. Name for ethanal






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






33. Goal is to produce most stable carbocation


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






35. Lowest priority group projects into the page






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






37. M - chloroperoxybenzoic acid






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






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






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






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






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. Spatial arrangement of the atoms or groups of a sterioisomer






44. Combustion reaction occurs through a radical process






45. Formed by mixing different types of orbitals






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






47. What is produced when o3 with lialh4 or nabh4






48. 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






49. Not solvated






50. Carbon carbon triple bonds. Suffix-yne.
