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. Most favorable of staggared conformations






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






3. Refers to the =CH2 group






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






5. A = observed rotation / concentration * length






6. 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.






7. Solvents with protons in solution - e.g. water or alcohol. large atoms tend to be better nucleophiles in here because they can shed the solvating protons around them and are more polarizable






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






9. Goal is to produce most stable carbocation

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






11. Diols with hydroxyl group on adjacent carbon






12. One s and two p 120 degree apart






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






14. A molecule with an internal plane of symmetry






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






16. 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






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

18. One s and three p orbitals






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






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






21. Iso - neo - cyclo






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






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






24. No double bonds. it has the maximum number of hydrogens.






25. Methyl are 60 degrees apart. kinda stable






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






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






28. Kmno4






29. What is produced when o3 with lialh4 or nabh4






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






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






32. M - chloroperoxybenzoic acid






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






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






35. Compounds with halogen






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






37. Alphabetical order of alkane rxn






38. Same molecular formula but different structure






39. Lowest priority group projects into the page






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






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






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






43. Diol with hydroxyl group on same carbon






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






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






46. Not solvated






47. 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-






48. Two hydroxyl groups






49. Highest energy no separation. or 120 separation.






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