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






2. 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.






3. O3






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






5. When boat flips






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






7. Carbon double bonded to an oxygen






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






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






10. Alphabetical order of alkane rxn






11. Diol with hydroxyl group on same carbon






12. F - CL - Br - I






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






14. A sigma bond and two pi bonds






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






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






17. Same molecular formula but different structure






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






19. Name for mathanal






20. Iso - neo - cyclo






21. Carbon carbon triple bonds. Suffix-yne.






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






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






24. Two p orbital form pi and third p orbital combine with s to make two sp hybrid. 180 degree apart






25. Diols with hydroxyl group on adjacent carbon






26. Methyl are 60 degrees apart. kinda stable






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






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






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






30. What are the best leaving groups?






31. 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-






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






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






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






36. 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






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






38. Two hydroxyl groups






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






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






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






42. Transfer of electrions from one atome to another






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






44. Steps of free radical substitution






45. N - l - ml - ms






46. Combustion reaction occurs through a radical process






47. Formed by mixing different types of orbitals






48. Name for propanal






49. Charged - need electrons






50. 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
