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. Methyl are 60 degrees apart. kinda stable






2. Name for ethanal






3. Carbon double bonded to an oxygen






4. Carbon carbon triple bonds. Suffix-yne.






5. N - l - ml - ms






6. 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.






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






8. Is bonded to only one other carbon atom






9. Diols with hydroxyl group on adjacent carbon






10. Steps of free radical substitution






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






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






13. Compounds with halogen






14. Transfer of electrions from one atome to another






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






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






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






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






19. Kmno4






20. Common name for ethyne






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






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






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






24. Two hydroxyl groups






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






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






27. One s and two p 120 degree apart






28. Monosubstituted ethylene






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






30. A molecule with an internal plane of symmetry






31. Charged - need electrons






32. Refers to the =CH2 group






33. One s and three p orbitals






34. Same molecular formula but different structure






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






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






37. Combustion reaction occurs through a radical process






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






39. O3






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






41. A = observed rotation / concentration * length






42. Not solvated






43. Formed by mixing different types of orbitals






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






45. Iso - neo - cyclo






46. Name for propanal






47. Rotations cancel each other out therefore no optical activity






48. 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






49. 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






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