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






2. Lowest priority group projects into the page






3. Steps of free radical substitution






4. Object that is not superimposable upon mirror image






5. A sigma bond and two pi bonds






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






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






8. A = observed rotation / concentration * length






9. Name for ethanal






10. What are the best leaving groups?






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






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






13. Highest energy no separation. or 120 separation.






14. Kmno4






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






16. M - chloroperoxybenzoic acid






17. Not solvated






18. When bond angles deviate from ideal values






19. Alkene oxidized with this - strong oxidizing agent. CH3CO3H or mcpba and it makes epoxide or oxirane






20. Diols with hydroxyl group on adjacent carbon






21. N - l - ml - ms






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






23. Two hydroxyl groups






24. What is produced when o3 with lialh4 or nabh4






25. Diol with hydroxyl group on same carbon






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






27. Transfer of electrions from one atome to another






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






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






30. Is bonded to only one other carbon atom






31. Monosubstituted ethylene






32. Zn/h or CH3/s with ozonolysis






33. 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.






34. 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






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






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






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






38. 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






39. Iso - neo - cyclo






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






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






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






43. Common name for ethyne






44. A molecule with an internal plane of symmetry






45. Y = position of double bond - x is position of triple bond - root is the prefix representing the length of the principal carbon chain






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


47. If reagent has a bunch of oxygen






48. 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






49. When boat flips






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