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. Object that is not superimposable upon mirror image






2. 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






3. Compounds with halogen






4. Refers to the =CH2 group






5. M - chloroperoxybenzoic acid






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






7. 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.






8. Di - tri - t - sec - n -






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






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






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






12. A = observed rotation / concentration * length






13. Sharing of electron between atoms






14. Carbon double bonded to an oxygen






15. Most favorable of staggared conformations






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






17. 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






18. Functionality is specified by alkoxy- prefix. ROR






19. 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-






20. One s and two p 120 degree apart






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






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






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






24. Kmno4






25. Not solvated






26. Monosubstituted ethylene






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






28. Name for propanal






29. Same molecular formula but different structure






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






31. Name for ethanal






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






33. 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






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






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






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






37. Two hydroxyl groups






38. Diols with hydroxyl group on adjacent carbon






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






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






41. Lowest priority group projects into the page






42. Rotations cancel each other out therefore no optical activity






43. Highest energy no separation. or 120 separation.






44. Iso - neo - cyclo






45. One s and three p orbitals






46. Charged - need electrons






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






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






49. When boat flips






50. Combustion reaction occurs through a radical process
