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. Refers to the =CH2 group






2. Two hydroxyl groups






3. Reducing an alkene by adding molecular hydrogen to double bond with aid of metal catalyst. e.g. pt - pd - ni. takes place on surface of metal so it does syn addition






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






5. Transfer of electrions from one atome to another






6. If reagent has a bunch of oxygen






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






8. Alkene oxidized with this - strong oxidizing agent. CH3CO3H or mcpba and it makes epoxide or oxirane






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






10. Monosubstituted ethylene






11. 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.






12. Zn/h or CH3/s with ozonolysis






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






14. Not solvated






15. A sigma bond and two pi bonds






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






17. Name for propanal






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






19. Highest energy no separation. or 120 separation.






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. Iso - neo - cyclo






23. What is produced when o3 with lialh4 or nabh4






24. When bond angles deviate from ideal values






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






26. Is bonded to only one other carbon atom






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






28. Charged - need electrons






29. 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






30. M - chloroperoxybenzoic acid






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






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






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






34. Diols with hydroxyl group on adjacent carbon






35. When boat flips






36. Common name for ethyne






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






38. Di - tri - t - sec - n -






39. 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






40. A molecule with an internal plane of symmetry






41. Combustion reaction occurs through a radical process






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






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






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






45. O3






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






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






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






49. A = observed rotation / concentration * length






50. Most favorable of staggared conformations
