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. 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






2. Same molecular formula but different structure






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






4. F - CL - Br - I






5. When bond angles deviate from ideal values






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






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






8. Carbon carbon triple bonds. Suffix-yne.






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






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






11. 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.






12. Lowest priority group projects into the page






13. O3






14. Functionality is specified by alkoxy- prefix. ROR






15. Iso - neo - cyclo






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






17. Two hydroxyl groups






18. Methyl are 60 degrees apart. kinda stable






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






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






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






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






23. Refers to the =CH2 group






24. 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-






25. Rotations cancel each other out therefore no optical activity






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






27. Compounds with halogen






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






29. Sharing of electron between atoms






30. Name for propanal






31. Combustion reaction occurs through a radical process






32. Name for mathanal






33. Alphabetical order of alkane rxn






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

35. A sigma bond and two pi bonds






36. Kmno4






37. 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






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






39. Steps of free radical substitution






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






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






42. Is bonded to only one other carbon atom






43. Monosubstituted ethylene






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






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






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






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






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






49. What is produced when o3 with lialh4 or nabh4






50. Highest energy no separation. or 120 separation.
