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






2. Functionality is specified by alkoxy- prefix. ROR






3. No double bonds. it has the maximum number of hydrogens.






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






5. 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






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






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






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






9. Most favorable of staggared conformations






10. Carbon double bonded to an oxygen






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






12. Common name for ethyne






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






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






15. 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-






16. Hydrocarbon with one or more carbon carbon triple bond






17. When boat flips






18. Highest energy no separation. or 120 separation.






19. 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






20. If reagent has a bunch of oxygen






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






22. F - CL - Br - I






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






24. Name for propanal






25. One s and three p orbitals






26. Arise from angle strain - torsional strian and nonbonded strain






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


28. N - l - ml - ms






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






30. Sharing of electron between atoms






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






32. 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






33. Object that is not superimposable upon mirror image






34. Diol with hydroxyl group on same carbon






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






36. Goal is to produce most stable carbocation


37. Rotations cancel each other out therefore no optical activity






38. Same molecular formula but different structure






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






40. A = observed rotation / concentration * length






41. Lowest priority group projects into the page






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






43. Monosubstituted ethylene






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






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






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






47. Carbon carbon triple bonds. Suffix-yne.






48. Name for mathanal






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






50. Iso - neo - cyclo
