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. 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






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






3. Transfer of electrions from one atome to another






4. Methyl are 60 degrees apart. kinda stable






5. Carbon carbon triple bonds. Suffix-yne.






6. 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-






7. Name for mathanal






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






9. O3






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






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






12. When boat flips






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






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






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






16. Di - tri - t - sec - n -






17. Compounds with halogen






18. One s and three p orbitals






19. 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.






20. When bond angles deviate from ideal values






21. Iso - neo - cyclo






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






23. Not solvated






24. N - l - ml - ms






25. If reagent has a bunch of oxygen






26. Functionality is specified by alkoxy- prefix. ROR






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






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






29. Most favorable of staggared conformations






30. One s and two p 120 degree apart






31. 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






32. Refers to the =CH2 group






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






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






35. What is produced when o3 with lialh4 or nabh4






36. A molecule with an internal plane of symmetry






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






38. Zn/h or CH3/s with ozonolysis






39. F - CL - Br - I






40. A = observed rotation / concentration * length






41. Carbon double bonded to an oxygen






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






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






44. 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






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






46. 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.






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






48. Lowest priority group projects into the page






49. Kmno4






50. 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.
