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. Common name for ethyne






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






3. Charged - need electrons






4. What is produced when o3 with lialh4 or nabh4






5. Monosubstituted ethylene






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






7. What are the best leaving groups?






8. Two hydroxyl groups






9. Lowest priority group projects into the page






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






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






12. Refers to the =CH2 group






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






14. Same molecular formula but different structure






15. A molecule with an internal plane of symmetry






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






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






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






19. Is bonded to only one other carbon atom






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






21. When bond angles deviate from ideal values






22. Functionality is specified by alkoxy- prefix. ROR






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






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






25. Transfer of electrions from one atome to another






26. Kmno4






27. Steps of free radical substitution






28. Iso - neo - cyclo






29. Zn/h or CH3/s with ozonolysis






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






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






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






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






34. Formed by mixing different types of orbitals






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






36. Most favorable of staggared conformations






37. 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-






38. One s and two p 120 degree apart






39. 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






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






41. Name for ethanal






42. Object that is not superimposable upon mirror image






43. M - chloroperoxybenzoic acid






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






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






46. A sigma bond and two pi bonds






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






48. Combustion reaction occurs through a radical process






49. Goal is to produce most stable carbocation


50. One s and three p orbitals
