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. Zn/h or CH3/s with ozonolysis






2. What are the best leaving groups?






3. Common name for ethyne






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






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






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






7. Object that is not superimposable upon mirror image






8. Name for ethanal






9. Monosubstituted ethylene






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






11. Di - tri - t - sec - n -






12. One s and two p 120 degree apart






13. Kmno4






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






15. Two hydroxyl groups






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






17. Nonterminal alkenes are cleaved to form two molar equivalent of carvoxylic acid ..make keton






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






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






20. Most favorable of staggared conformations






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






22. Hydrocarbon with one or more carbon carbon triple bond






23. Same molecular formula but different structure






24. F - CL - Br - I






25. Is bonded to only one other carbon atom






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






27. Name for mathanal






28. 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.






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






30. When bond angles deviate from ideal values






31. Highest energy no separation. or 120 separation.






32. 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






33. Compounds with halogen






34. When boat flips






35. M - chloroperoxybenzoic acid






36. 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






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






38. Lowest priority group projects into the page






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






40. Carbon carbon triple bonds. Suffix-yne.






41. Formed by mixing different types of orbitals






42. Steps of free radical substitution






43. Water can be added to alkenes under acidic conditions. make carbocation. ends with alcohol






44. 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-






45. Combustion reaction occurs through a radical process






46. A molecule with an internal plane of symmetry






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






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






49. One s and three p orbitals






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