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. Functionality is specified by alkoxy- prefix. ROR






2. Methyl are 60 degrees apart. kinda stable






3. A = observed rotation / concentration * length






4. Rotations cancel each other out therefore no optical activity






5. Sharing of electron between atoms






6. What is produced when o3 with lialh4 or nabh4






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






8. Two hydroxyl groups






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






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






11. 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.






12. Common name for ethyne






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






14. Kmno4






15. When boat flips






16. Zn/h or CH3/s with ozonolysis






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






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






19. What are the best leaving groups?






20. Most favorable of staggared conformations






21. If reagent has a bunch of oxygen






22. 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






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






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






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






26. Hydrocarbon with one or more carbon carbon triple bond






27. 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-






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






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






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






31. Diols with hydroxyl group on adjacent carbon






32. 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.






33. F - CL - Br - I






34. Name for mathanal






35. Highest energy no separation. or 120 separation.






36. Combustion reaction occurs through a radical process






37. M - chloroperoxybenzoic acid






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






39. Is bonded to only one other carbon atom






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






41. 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






42. Palladium or barium sulfate (BaSO4) with quinoline. occur on metal surface - make cis.

43. 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.






44. Diol with hydroxyl group on same carbon






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






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






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






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






49. Steps of free radical substitution






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