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






2. Common name for ethyne






3. Rotations cancel each other out therefore no optical activity






4. Name for ethanal






5. 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.






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






7. One s and two p 120 degree apart






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

9. M - chloroperoxybenzoic acid






10. Sharing of electron between atoms






11. O3






12. Lowest priority group projects into the page






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






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






15. Name for propanal






16. A molecule with an internal plane of symmetry






17. 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






18. If reagent has a bunch of oxygen






19. In which one or morehydrogen atoms are replaced with a halogen atom. via free radical substitution






20. 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.






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






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






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






24. Monosubstituted ethylene






25. One s and three p orbitals






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






27. N - l - ml - ms






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






29. 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






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






31. When boat flips






32. A = observed rotation / concentration * length






33. Iso - neo - cyclo






34. Zn/h or CH3/s with ozonolysis






35. Goal is to produce most stable carbocation

36. Not solvated






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






38. Functionality is specified by alkoxy- prefix. ROR






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






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






41. Carbon double bonded to an oxygen






42. 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






43. Most favorable of staggared conformations






44. Kmno4






45. Transfer of electrions from one atome to another






46. Formed by mixing different types of orbitals






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






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






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






50. Di - tri - t - sec - n -
