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. N - l - ml - ms






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






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






4. 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






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






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






7. Reducing an alkene by adding molecular hydrogen to double bond with aid of metal catalyst. e.g. pt - pd - ni. takes place on surface of metal so it does syn addition






8. Monosubstituted ethylene






9. Ozonolysis under hot acidic kmO4 - e.g. H2O2 condition






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






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






12. Lowest priority group projects into the page






13. Kmno4






14. Steps of free radical substitution






15. Refers to the =CH2 group






16. Transfer of electrions from one atome to another






17. Combustion reaction occurs through a radical process






18. Name for propanal






19. F - CL - Br - I






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






21. Is bonded to only one other carbon atom






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






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






24. When boat flips






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






26. Name for mathanal






27. 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






28. One s and two p 120 degree apart






29. Diol with hydroxyl group on same carbon






30. Hydrocarbon with one or more carbon carbon triple bond






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






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






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






34. Results when nonadjacent atoms or groups compete for space. dominant source of energy in flagpole interactions of the boat conformation. thus it goes in various conformations like chair boat and twist.






35. Alphabetical order of alkane rxn






36. Charged - need electrons






37. If reagent has a bunch of oxygen






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






39. Zn/h or CH3/s with ozonolysis






40. One s and three p orbitals






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






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






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






44. 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.






45. A = observed rotation / concentration * length






46. Object that is not superimposable upon mirror image






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






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






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






50. A molecule with an internal plane of symmetry
