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. Name for mathanal






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






3. Two hydroxyl groups






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






5. What is produced when o3 with lialh4 or nabh4






6. Carbon carbon triple bonds. Suffix-yne.






7. Transfer of electrions from one atome to another






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






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






10. What are the best leaving groups?






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






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






13. One s and three p orbitals






14. 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






15. A = observed rotation / concentration * length






16. 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






17. Is bonded to only one other carbon atom






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






19. Common name for ethyne






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






21. Palladium or barium sulfate (BaSO4) with quinoline. occur on metal surface - make cis.

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






23. Configuration in relation to another chiral molecule. use it to determine if a molecule is an enantiomer - diastereomer - etc






24. 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.






25. Diol with hydroxyl group on same carbon






26. Lowest priority group projects into the page






27. Combustion reaction occurs through a radical process






28. If reagent has a bunch of oxygen






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






30. 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






31. Object that is not superimposable upon mirror image






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






33. M - chloroperoxybenzoic acid






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






35. Highest energy no separation. or 120 separation.






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






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






38. Sharing of electron between atoms






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. Most favorable of staggared conformations






41. A molecule with an internal plane of symmetry






42. Compounds with halogen






43. Hydrocarbon with one or more carbon carbon triple bond






44. Diols with hydroxyl group on adjacent carbon






45. Kmno4






46. O3






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






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






49. Methyl are 60 degrees apart. kinda stable






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