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. Combustion reaction occurs through a radical process






2. Functionality is specified by alkoxy- prefix. ROR






3. Alphabetical order of alkane rxn






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






5. 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






6. Diols with hydroxyl group on adjacent carbon






7. Name for propanal






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






9. 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-






10. When two atomic orbitals combine. obtained mathematically by adding or subtracting wave functions. if sings are the same - make bonding - if different - less stable antibonding.






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






12. Compounds with halogen






13. In presence of peroxide - oxygen or ultraviolet light. antimarkonikov because they want a stable free radical. therefore X ends up on least subsituted carbon






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






15. Goal is to produce most stable carbocation

16. 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






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






18. N - l - ml - ms






19. One s and two p 120 degree apart






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






21. Methyl are 60 degrees apart. kinda stable






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






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






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






25. Zn/h or CH3/s with ozonolysis






26. O3






27. Lowest priority group projects into the page






28. If reagent has a bunch of oxygen






29. 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






30. Alkenes oxidzed with kmno4 - if made with cold - dilue - make OH on each side of double bond - diols or glycol in syn orientation






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






32. Diol with hydroxyl group on same carbon






33. One s and three p orbitals






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






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






36. Common name for ethyne






37. Hydrocarbon with one or more carbon carbon triple bond






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






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






40. 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.






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






42. 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






43. Monosubstituted ethylene






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






45. Refers to the =CH2 group






46. Two hydroxyl groups






47. Name for ethanal






48. When bond angles deviate from ideal values






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






50. Carbon double bonded to an oxygen
