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. Carbon carbon triple bonds. Suffix-yne.






2. 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






3. Two p orbital form pi and third p orbital combine with s to make two sp hybrid. 180 degree apart






4. Goal is to produce most stable carbocation


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






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






7. Highest energy no separation. or 120 separation.






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






9. What are the best leaving groups?






10. Combustion reaction occurs through a radical process






11. 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.






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






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






14. 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.






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






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






17. Refers to the =CH2 group






18. Steps of free radical substitution






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






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






21. Charged - need electrons






22. If reagent has a bunch of oxygen






23. Name for propanal






24. A sigma bond and two pi bonds






25. Same molecular formula but different structure






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






27. Kmno4






28. When boat flips






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






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






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






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






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






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






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






36. Diol with hydroxyl group on same carbon






37. One s and three p orbitals






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






39. A molecule with an internal plane of symmetry






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






41. Functionality is specified by alkoxy- prefix. ROR






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






43. Diols with hydroxyl group on adjacent carbon






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






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






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






47. A = observed rotation / concentration * length






48. Alphabetical order of alkane rxn






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






50. Rotations cancel each other out therefore no optical activity
