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. Diols with hydroxyl group on adjacent carbon






2. 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-






3. Methyl are 60 degrees apart. kinda stable






4. Common name for ethyne






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






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






7. 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






8. Charged - need electrons






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






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






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






12. 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






13. If reagent has a bunch of oxygen






14. N - l - ml - ms






15. Lowest priority group projects into the page






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






17. 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






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






19. Not solvated






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






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






22. 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






23. Object that is not superimposable upon mirror image






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

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






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






27. 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.






28. Highest energy no separation. or 120 separation.






29. F - CL - Br - I






30. A molecule with an internal plane of symmetry






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






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






33. When bond angles deviate from ideal values






34. A = observed rotation / concentration * length






35. One s and two p 120 degree apart






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






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






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






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






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






41. Refers to the =CH2 group






42. Two hydroxyl groups






43. 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.






44. Formed by mixing different types of orbitals






45. Name for propanal






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






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






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






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






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