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






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






3. Transfer of electrions from one atome to another






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






5. F - CL - Br - I






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

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






8. 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






9. O3






10. Common name for ethyne






11. A sigma bond and two pi bonds






12. A = observed rotation / concentration * length






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






14. Rotations cancel each other out therefore no optical activity






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






16. Functionality is specified by alkoxy- prefix. ROR






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






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






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






20. Is bonded to only one other carbon atom






21. Name for propanal






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






23. Alphabetical order of alkane rxn






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






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






26. Iso - neo - cyclo






27. Charged - need electrons






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






29. Most favorable of staggared conformations






30. Sharing of electron between atoms






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






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






33. 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






34. Carbonyl located at the end of the chain named by replacing al with e. e.g. butanal






35. What is produced when o3 with lialh4 or nabh4






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






37. Carbon double bonded to an oxygen






38. One s and three p orbitals






39. When bond angles deviate from ideal values






40. Carbon carbon triple bonds. Suffix-yne.






41. M - chloroperoxybenzoic acid






42. What are the best leaving groups?






43. Name for ethanal






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






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






46. A molecule with an internal plane of symmetry






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






48. 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.






49. Hydrocarbon with one or more carbon carbon triple bond






50. When boat flips
