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






2. One s and three p orbitals






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






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






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






6. Charged - need electrons






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






8. Kmno4






9. More likely it is to attract positively charged proton. nucleophilic strength decreses: RO->HO>RCO2>ROH>H2O






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






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






12. Methyl are 60 degrees apart. kinda stable






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






14. Diols with hydroxyl group on adjacent carbon






15. 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-






16. Name for mathanal






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






18. Not solvated






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






20. 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.






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






22. When boat flips






23. Carbon carbon triple bonds. Suffix-yne.






24. Name for propanal






25. Most favorable of staggared conformations






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






27. When bond angles deviate from ideal values






28. If reagent has a bunch of oxygen






29. Di - tri - t - sec - n -






30. Diol with hydroxyl group on same carbon






31. Is bonded to only one other carbon atom






32. Sharing of electron between atoms






33. Object that is not superimposable upon mirror image






34. Alphabetical order of alkane rxn






35. N - l - ml - ms






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






37. Compounds with halogen






38. Transfer of electrions from one atome to another






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






40. A = observed rotation / concentration * length






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






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






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






44. Lowest priority group projects into the page






45. Refers to the =CH2 group






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






47. Rotations cancel each other out therefore no optical activity






48. A sigma bond and two pi bonds






49. 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






50. Same molecular formula but different structure
