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






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






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






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






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






6. Name for propanal






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






8. Diol with hydroxyl group on same carbon






9. One s and two p 120 degree apart






10. Iso - neo - cyclo






11. What are the best leaving groups?






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






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






14. Hydrocarbon with one or more carbon carbon triple bond






15. A molecule with an internal plane of symmetry






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






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






18. 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.






19. Name for ethanal






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






21. A = observed rotation / concentration * length






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

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






24. Two hydroxyl groups






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






26. Name for mathanal






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






28. If reagent has a bunch of oxygen






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






30. Sharing of electron between atoms






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






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






33. Transfer of electrions from one atome to another






34. Alphabetical order of alkane rxn






35. 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






36. Functionality is specified by alkoxy- prefix. ROR






37. Is bonded to only one other carbon atom






38. Carbon double bonded to an oxygen






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






40. Diols with hydroxyl group on adjacent carbon






41. 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.






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






43. When boat flips






44. N - l - ml - ms






45. Compounds with halogen






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






47. Charged - need electrons






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






49. Common name for ethyne






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