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. Name for propanal






2. Not solvated






3. Common name for ethyne






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






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






6. Diols with hydroxyl group on adjacent carbon






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

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






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






10. Charged - need electrons






11. Object that is not superimposable upon mirror image






12. Formed by mixing different types of orbitals






13. Rotations cancel each other out therefore no optical activity






14. Compounds with halogen






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






16. Same molecular formula but different structure






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






18. A sigma bond and two pi bonds






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






20. Zn/h or CH3/s with ozonolysis






21. Functionality is specified by alkoxy- prefix. ROR






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






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






24. Kmno4






25. Refers to the =CH2 group






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






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






28. Carbon double bonded to an oxygen






29. One s and two p 120 degree apart






30. Diol with hydroxyl group on same carbon






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






32. Monosubstituted ethylene






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






34. Two hydroxyl groups






35. A molecule with an internal plane of symmetry






36. Carbon carbon triple bonds. Suffix-yne.






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






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






39. Most favorable of staggared conformations






40. Occur when a molecule is broken down by heat. used to reduce the avverage molecular weight of heavy oils. c - c - bonds are cleave dand make small chain alkyl radicals that recombine to form different alkanes






41. What is produced when o3 with lialh4 or nabh4






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






43. Methyl are 60 degrees apart. kinda stable






44. 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.






45. Steps of free radical substitution






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






47. Lowest priority group projects into the page






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






49. Goal is to produce most stable carbocation

50. Transfer of electrions from one atome to another
