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






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






3. Carbon double bonded to an oxygen






4. Functionality is specified by alkoxy- prefix. ROR






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






6. One s and three p orbitals






7. Diol with hydroxyl group on same carbon






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






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






10. Diols with hydroxyl group on adjacent carbon






11. Sharing of electron between atoms






12. Combustion reaction occurs through a radical process






13. Not solvated






14. What is produced when o3 with lialh4 or nabh4






15. Name for propanal






16. 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.






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






18. Common name for ethyne






19. Formed by mixing different types of orbitals






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






21. Goal is to produce most stable carbocation

22. Name for mathanal






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






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






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






26. Refers to the =CH2 group






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






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






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






30. Rotations cancel each other out therefore no optical activity






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






32. Steps of free radical substitution






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






34. When bond angles deviate from ideal values






35. Compounds with halogen






36. A sigma bond and two pi bonds






37. What are the best leaving groups?






38. 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






39. Di - tri - t - sec - n -






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






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






42. Most favorable of staggared conformations






43. 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






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






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






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






47. Object that is not superimposable upon mirror image






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






49. Alphabetical order of alkane rxn






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