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. Goal is to produce most stable carbocation

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






3. When bond angles deviate from ideal values






4. Lowest priority group projects into the page






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






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






7. One s and three p orbitals






8. M - chloroperoxybenzoic acid






9. Carbonyl located in middle or somewhere in chane. Named with One






10. A molecule with an internal plane of symmetry






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






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






13. Same molecular formula but different structure






14. 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






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






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






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






18. Sharing of electron between atoms






19. A sigma bond and two pi bonds






20. N - l - ml - ms






21. Common name for ethyne






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






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






24. Carbon carbon triple bonds. Suffix-yne.






25. Two hydroxyl groups






26. 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.






27. Charged - need electrons






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






29. 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.






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






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






32. Carbon double bonded to an oxygen






33. Zn/h or CH3/s with ozonolysis






34. 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-






35. Functionality is specified by alkoxy- prefix. ROR






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






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






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

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






40. Nonterminal alkenes are cleaved to form two molar equivalent of carvoxylic acid ..make keton






41. Name for ethanal






42. 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.






43. Di - tri - t - sec - n -






44. A = observed rotation / concentration * length






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






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






47. 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






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






49. Name for propanal






50. Is bonded to only one other carbon atom
