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. Spatial arrangement of the atoms or groups of a sterioisomer






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






4. Is bonded to only one other carbon atom






5. Methyl are 60 degrees apart. kinda stable






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






7. Highest energy no separation. or 120 separation.






8. Goal is to produce most stable carbocation

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






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






11. F - CL - Br - I






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






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






14. Formed by mixing different types of orbitals






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






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






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






18. Charged - need electrons






19. Alphabetical order of alkane rxn






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






21. 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-






22. Two hydroxyl groups






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






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






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






26. Carbon double bonded to an oxygen






27. If reagent has a bunch of oxygen






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






29. Object that is not superimposable upon mirror image






30. 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






31. Common name for ethyne






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






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. Zn/h or CH3/s with ozonolysis






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






36. Lowest priority group projects into the page






37. When boat flips






38. Diol with hydroxyl group on same carbon






39. Not solvated






40. Hydrocarbon with one or more carbon carbon triple bond






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






42. Kmno4






43. Compounds with halogen






44. Name for mathanal






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






46. A molecule with an internal plane of symmetry






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






48. M - chloroperoxybenzoic acid






49. Sharing of electron between atoms






50. Functionality is specified by alkoxy- prefix. ROR
