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. Functionality is specified by alkoxy- prefix. ROR






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






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






4. Two hydroxyl groups






5. Carbon double bonded to an oxygen






6. Name for propanal






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






8. Iso - neo - cyclo






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






10. Same molecular formula but different structure






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






12. 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






13. One s and three p orbitals






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






15. When bond angles deviate from ideal values






16. One s and two p 120 degree apart






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






18. Zn/h or CH3/s with ozonolysis






19. Di - tri - t - sec - n -






20. 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-






21. Three different substitutents often have plane of symmetry. and rotation of 180 will allow molecule to be superimposed on mirror image






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






23. Refers to the =CH2 group






24. O3






25. Sharing of electron between atoms






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






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






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






29. Is bonded to only one other carbon atom






30. Diol with hydroxyl group on same carbon






31. Compounds with halogen






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






33. When boat flips






34. Steps of free radical substitution






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






36. Most favorable of staggared conformations






37. What is produced when o3 with lialh4 or nabh4






38. F - CL - Br - I






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






40. 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.






41. 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.






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






43. Charged - need electrons






44. Nonterminal alkenes are cleaved to form two molar equivalent of carvoxylic acid ..make keton






45. Transfer of electrions from one atome to another






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






47. A sigma bond and two pi bonds






48. A molecule with an internal plane of symmetry






49. Alphabetical order of alkane rxn






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