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. Transfer of electrions from one atome to another






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






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






4. Zn/h or CH3/s with ozonolysis






5. Formed by mixing different types of orbitals






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






7. Object that is not superimposable upon mirror image






8. M - chloroperoxybenzoic acid






9. Same molecular formula but different structure






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






11. When bond angles deviate from ideal values






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






13. When boat flips






14. Functionality is specified by alkoxy- prefix. ROR






15. One s and two p 120 degree apart






16. Combustion reaction occurs through a radical process






17. 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






18. 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.






19. Diols with hydroxyl group on adjacent carbon






20. 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-






21. Most favorable of staggared conformations






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






23. Methyl are 60 degrees apart. kinda stable






24. Monosubstituted ethylene






25. Results when cyclic molecules must assume conformations that have eclipsed interactions






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






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






28. Name for ethanal






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






30. Diol with hydroxyl group on same carbon






31. Steps of free radical substitution






32. What are the best leaving groups?






33. Goal is to produce most stable carbocation

34. Name for mathanal






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






36. Always receive number one. contain carbonyl and OH group - very oxidized. highest priority functional group.






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






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






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






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






41. If reagent has a bunch of oxygen






42. Iso - neo - cyclo






43. Carbon carbon triple bonds. Suffix-yne.






44. Alphabetical order of alkane rxn






45. 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






46. Common name for ethyne






47. 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






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






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






50. Name for propanal
