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






2. Compounds with halogen






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






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






6. Highest energy no separation. or 120 separation.






7. O3






8. Monosubstituted ethylene






9. Not solvated






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






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

12. 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






13. 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.






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






15. A = observed rotation / concentration * length






16. 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.






17. Functionality is specified by alkoxy- prefix. ROR






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






19. One s and two p 120 degree apart






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. Di - tri - t - sec - n -






22. Steps of free radical substitution






23. Diol with hydroxyl group on same carbon






24. What is produced when o3 with lialh4 or nabh4






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. 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






27. Transfer of electrions from one atome to another






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






29. Hydrocarbon with one or more carbon carbon triple bond






30. Carbon double bonded to an oxygen






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






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






33. Rotations cancel each other out therefore no optical activity






34. Combustion reaction occurs through a radical process






35. 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






36. Same molecular formula but different structure






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






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






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






40. F - CL - Br - I






41. Refers to the =CH2 group






42. Alphabetical order of alkane rxn






43. Object that is not superimposable upon mirror image






44. Sharing of electron between atoms






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






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






47. More likely it is to attract positively charged proton. nucleophilic strength decreses: RO->HO>RCO2>ROH>H2O






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






49. Charged - need electrons






50. Fast process. double bond is nucleophile and attack x2. make cyclic halonium ion with either br or cl. and make dihalo trans
