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






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






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






4. Is bonded to only one other carbon atom






5. One s and three p orbitals






6. Di - tri - t - sec - n -






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






8. Object that is not superimposable upon mirror image






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






10. A = observed rotation / concentration * length






11. Kmno4






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






13. A sigma bond and two pi bonds






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






15. What are the best leaving groups?






16. Not solvated






17. Most favorable of staggared conformations






18. Compounds with halogen






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






20. Same molecular formula but different structure






21. If reagent has a bunch of oxygen






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






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






24. Propylenes attached to a backbone at the C-3 position. Meaning the double bond at end of the chain and single bonded carbon at rest






25. Zn/h or CH3/s with ozonolysis






26. F - CL - Br - I






27. Hydrocarbon with one or more carbon carbon triple bond






28. Rotations cancel each other out therefore no optical activity






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






30. Diol with hydroxyl group on same carbon






31. N - l - ml - ms






32. Sharing of electron between atoms






33. 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






34. Alphabetical order of alkane rxn






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






36. Highest energy no separation. or 120 separation.






37. Name for mathanal






38. Steps of free radical substitution






39. 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-






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






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






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






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






44. M - chloroperoxybenzoic acid






45. Monosubstituted ethylene






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






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






48. What is produced when o3 with lialh4 or nabh4






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






50. Share molecular formula but have different chemical and physical properties
