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






2. What is produced when o3 with lialh4 or nabh4






3. Diol with hydroxyl group on same carbon






4. Formed by mixing different types of orbitals






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






6. 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-






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






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






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






10. More likely it is to attract positively charged proton. nucleophilic strength decreses: RO->HO>RCO2>ROH>H2O






11. When boat flips






12. N - l - ml - ms






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






14. Same molecular formula but different structure






15. 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.






16. Di - tri - t - sec - n -






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






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






19. Name for propanal






20. Sharing of electron between atoms






21. Common name for ethyne






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






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






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






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






26. 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






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






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






29. Transfer of electrions from one atome to another






30. M - chloroperoxybenzoic acid






31. One s and three p orbitals






32. Zn/h or CH3/s with ozonolysis






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






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






35. Carbon carbon triple bonds. Suffix-yne.






36. When bond angles deviate from ideal values






37. If reagent has a bunch of oxygen






38. Carbon double bonded to an oxygen






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






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






41. Steps of free radical substitution






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






43. Results when nonadjacent atoms or groups compete for space. dominant source of energy in flagpole interactions of the boat conformation. thus it goes in various conformations like chair boat and twist.






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






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






46. F - CL - Br - I






47. Methyl are 60 degrees apart. kinda stable






48. Iso - neo - cyclo






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






50. What are the best leaving groups?
