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






2. Iso - neo - cyclo






3. Monosubstituted ethylene






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






5. Kmno4






6. Diols with hydroxyl group on adjacent carbon






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






8. Sharing of electron between atoms






9. Steps of free radical substitution






10. Transfer of electrions from one atome to another






11. 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.






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






13. Hydrocarbon with one or more carbon carbon triple bond






14. Charged - need electrons






15. Alphabetical order of alkane rxn






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






17. A = observed rotation / concentration * length






18. Carbon double bonded to an oxygen






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






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






21. Most favorable of staggared conformations






22. Not solvated






23. N - l - ml - ms






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






25. Methyl are 60 degrees apart. kinda stable






26. 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






27. Refers to the =CH2 group






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






29. 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






30. What are the best leaving groups?






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






32. Same molecular formula but different structure






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






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






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






36. Formed by mixing different types of orbitals






37. A sigma bond and two pi bonds






38. 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-






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






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






41. E of double bond act as lewis base and react with hydrogen of hx. make carbocation intermediate. use markonikovs rule






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






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






44. Common name for ethyne






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






46. Carbon carbon triple bonds. Suffix-yne.






47. Combustion reaction occurs through a radical process






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. Arise from angle strain - torsional strian and nonbonded strain
