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






2. Compounds with halogen






3. Name for mathanal






4. Diol with hydroxyl group on same carbon






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






6. Transfer of electrions from one atome to another






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






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






9. F - CL - Br - I






10. Monosubstituted ethylene






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






12. Most favorable of staggared conformations






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


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






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






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. Lowest priority group projects into the page






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






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






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






21. Diols with hydroxyl group on adjacent carbon






22. Alphabetical order of alkane rxn






23. 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.






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






25. Kmno4






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






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. 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






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






30. 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






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






32. Methyl are 60 degrees apart. kinda stable






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






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






35. Steps of free radical substitution






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






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






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






39. Common name for ethyne






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






41. Two hydroxyl groups






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






43. What are the best leaving groups?






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






45. Carbon carbon triple bonds. Suffix-yne.






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






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






48. Carbon double bonded to an oxygen






49. Goal is to produce most stable carbocation


50. Di - tri - t - sec - n -
