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






2. Carbon double bonded to an oxygen






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






4. Hydrocarbon with one or more carbon carbon triple bond






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






6. Diol with hydroxyl group on same carbon






7. Formed by mixing different types of orbitals






8. Not solvated






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






10. When bond angles deviate from ideal values






11. 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.






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






13. Charged - need electrons






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






15. Fast process. double bond is nucleophile and attack x2. make cyclic halonium ion with either br or cl. and make dihalo trans






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






17. M - chloroperoxybenzoic acid






18. One s and two p 120 degree apart






19. Lowest priority group projects into the page






20. A sigma bond and two pi bonds






21. Diols with hydroxyl group on adjacent carbon






22. Zn/h or CH3/s with ozonolysis






23. When boat flips






24. 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






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






26. Common name for ethyne






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






28. 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






29. A molecule with an internal plane of symmetry






30. 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.






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






32. N - l - ml - ms






33. Highest energy no separation. or 120 separation.






34. Name for propanal






35. 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






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






37. Combustion reaction occurs through a radical process






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






39. O3






40. Goal is to produce most stable carbocation


41. Most favorable of staggared conformations






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






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






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






45. Kmno4






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






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






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






49. Sharing of electron between atoms






50. Steps of free radical substitution
