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






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






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






4. Carbon double bonded to an oxygen






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






6. Lowest priority group projects into the page






7. Goal is to produce most stable carbocation


8. 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






9. Not solvated






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






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






12. 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.






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






14. 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-






15. Object that is not superimposable upon mirror image






16. 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.






17. One s and two p 120 degree apart






18. N - l - ml - ms






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






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






21. Refers to the =CH2 group






22. Alkene oxidized with this - strong oxidizing agent. CH3CO3H or mcpba and it makes epoxide or oxirane






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






24. One s and three p orbitals






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






26. Di - tri - t - sec - n -






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






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






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






30. 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






31. 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






32. A sigma bond and two pi bonds






33. Charged - need electrons






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






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






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






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






38. 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






39. Functionality is specified by alkoxy- prefix. ROR






40. Combustion reaction occurs through a radical process






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






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






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. Compounds with halogen






45. Name for mathanal






46. Same molecular formula but different structure






47. Kmno4






48. Diols with hydroxyl group on adjacent carbon






49. When bond angles deviate from ideal values






50. Carbon carbon triple bonds. Suffix-yne.
