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. One s and two p 120 degree apart






2. Name for propanal






3. A = observed rotation / concentration * length






4. Methyl are 60 degrees apart. kinda stable






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






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






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






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






9. Most favorable of staggared conformations






10. Combustion reaction occurs through a radical process






11. Steps of free radical substitution






12. 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.






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






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






15. A sigma bond and two pi bonds






16. When boat flips






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






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






19. What are the best leaving groups?






20. Water can be added to alkenes under acidic conditions. make carbocation. ends with alcohol






21. Zn/h or CH3/s with ozonolysis






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






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






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






25. Di - tri - t - sec - n -






26. Carbon double bonded to an oxygen






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






28. If reagent has a bunch of oxygen






29. N - l - ml - ms






30. Hydrocarbon with one or more carbon carbon triple bond






31. What is produced when o3 with lialh4 or nabh4






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






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






34. 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.






35. Charged - need electrons






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






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






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






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






40. M - chloroperoxybenzoic acid






41. One s and three p orbitals






42. Transfer of electrions from one atome to another






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






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






45. Lowest priority group projects into the page






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






47. Alphabetical order of alkane rxn






48. Monosubstituted ethylene






49. Sharing of electron between atoms






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