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






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






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






4. Functionality is specified by alkoxy- prefix. ROR






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






6. N - l - ml - ms






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

8. A molecule with an internal plane of symmetry






9. A = observed rotation / concentration * length






10. Carbon carbon triple bonds. Suffix-yne.






11. Iso - neo - cyclo






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






13. In which one or morehydrogen atoms are replaced with a halogen atom. via free radical substitution






14. Is bonded to only one other carbon atom






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






16. Steps of free radical substitution






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






18. Lowest priority group projects into the page






19. One s and two p 120 degree apart






20. If reagent has a bunch of oxygen






21. F - CL - Br - I






22. Compounds with halogen






23. Common name for ethyne






24. 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






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






26. 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.






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






28. Goal is to produce most stable carbocation

29. Methyl are 60 degrees apart. kinda stable






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






31. Name for mathanal






32. 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-






33. M - chloroperoxybenzoic acid






34. When bond angles deviate from ideal values






35. Refers to the =CH2 group






36. O3






37. Name for ethanal






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






39. 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






40. Object that is not superimposable upon mirror image






41. Two hydroxyl groups






42. Di - tri - t - sec - n -






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






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






45. Highest energy no separation. or 120 separation.






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






47. Solvents with protons in solution - e.g. water or alcohol. large atoms tend to be better nucleophiles in here because they can shed the solvating protons around them and are more polarizable






48. What are the best leaving groups?






49. Rotations cancel each other out therefore no optical activity






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