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. Kmno4






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






3. What are the best leaving groups?






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






5. Name for propanal






6. Not solvated






7. Goal is to produce most stable carbocation

8. Rotations cancel each other out therefore no optical activity






9. Transfer of electrions from one atome to another






10. 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-






11. A sigma bond and two pi bonds






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






13. When bond angles deviate from ideal values






14. 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.






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






16. Hydrocarbon with one or more carbon carbon triple bond






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






18. 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






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






20. Highest energy no separation. or 120 separation.






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






22. Carbon double bonded to an oxygen






23. Name for mathanal






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






25. Steps of free radical substitution






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






27. Carbon carbon triple bonds. Suffix-yne.






28. Di - tri - t - sec - n -






29. Same molecular formula but different structure






30. Monosubstituted ethylene






31. M - chloroperoxybenzoic acid






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






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






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






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






36. Two hydroxyl groups






37. Name for ethanal






38. O3






39. Nonsuperimposable mirror image of chiral objects - a specific steroisomer.






40. Alphabetical order of alkane rxn






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






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






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






44. N - l - ml - ms






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






46. What is produced when o3 with lialh4 or nabh4






47. Most favorable of staggared conformations






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






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