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. When bond angles deviate from ideal values






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






3. Goal is to produce most stable carbocation

4. One s and three p orbitals






5. Three different substitutents often have plane of symmetry. and rotation of 180 will allow molecule to be superimposed on mirror image






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






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






8. 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






9. Diol with hydroxyl group on same carbon






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






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






12. Combustion reaction occurs through a radical process






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






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






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






16. One s and two p 120 degree apart






17. Steps of free radical substitution






18. Two hydroxyl groups






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

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






21. 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.






22. If reagent has a bunch of oxygen






23. Name for propanal






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






25. Transfer of electrions from one atome to another






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






27. 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






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






29. Hydrocarbon with one or more carbon carbon triple bond






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






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






32. Diols with hydroxyl group on adjacent carbon






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






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






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






36. Compounds with halogen






37. O3






38. Kmno4






39. Alphabetical order of alkane rxn






40. Functionality is specified by alkoxy- prefix. ROR






41. Charged - need electrons






42. Name for mathanal






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






44. Common name for ethyne






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






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






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






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






49. Sharing of electron between atoms






50. Describes the exact spatial arrangement of groups of atoms independent of other molecules.
