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






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






3. Diborane add to double bond. boron acts as lewis acid and attaches to less hindered carbon. hydride transferred to adjacent carbon. antimarkonikov - alcohol produced






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






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






6. 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






7. Functionality is specified by alkoxy- prefix. ROR






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






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

10. Charged - need electrons






11. Object that is not superimposable upon mirror image






12. Transfer of electrions from one atome to another






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






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






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






16. Common name for ethyne






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






18. A = observed rotation / concentration * length






19. Alphabetical order of alkane rxn






20. 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-






21. A sigma bond and two pi bonds






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






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






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






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






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






27. Iso - neo - cyclo






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






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






30. 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.






31. 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.






32. Kmno4






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






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






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






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






37. Rotations cancel each other out therefore no optical activity






38. Di - tri - t - sec - n -






39. Hydrocarbon with one or more carbon carbon triple bond






40. Methyl are 60 degrees apart. kinda stable






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






42. Lowest priority group projects into the page






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






44. One s and three p orbitals






45. Formed by mixing different types of orbitals






46. Name for mathanal






47. Is bonded to only one other carbon atom






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






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






50. Same molecular formula but different structure
