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. 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






2. 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.






3. If reagent has a bunch of oxygen






4. Name for mathanal






5. Carbon carbon triple bonds. Suffix-yne.






6. Goal is to produce most stable carbocation

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






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






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






10. 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.






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






12. Di - tri - t - sec - n -






13. A molecule with an internal plane of symmetry






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






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






16. Carbon double bonded to an oxygen






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






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






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 three p orbitals






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






22. A sigma bond and two pi bonds






23. Iso - neo - cyclo






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






25. Functionality is specified by alkoxy- prefix. ROR






26. 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






27. Lowest priority group projects into the page






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






29. One s and two p 120 degree apart






30. Hydrocarbon with one or more carbon carbon triple bond






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






32. Kmno4






33. Is bonded to only one other carbon atom






34. Diol with hydroxyl group on same carbon






35. M - chloroperoxybenzoic acid






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






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






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






39. Alphabetical order of alkane rxn






40. What are the best leaving groups?






41. Methyl are 60 degrees apart. kinda stable






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






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






44. Two hydroxyl groups






45. 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






46. Most favorable of staggared conformations






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






48. Same molecular formula but different structure






49. Object that is not superimposable upon mirror image






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