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






2. 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






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






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






5. Lowest priority group projects into the page






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






7. Refers to the =CH2 group






8. Diols with hydroxyl group on adjacent carbon






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






10. Monosubstituted ethylene






11. Compounds with halogen






12. F - CL - Br - I






13. Name for mathanal






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






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


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






17. Name for propanal






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






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






20. M - chloroperoxybenzoic acid






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






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






23. 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






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






25. Sharing of electron between atoms






26. Charged - need electrons






27. Steps of free radical substitution






28. When two atomic orbitals combine. obtained mathematically by adding or subtracting wave functions. if sings are the same - make bonding - if different - less stable antibonding.






29. Two hydroxyl groups






30. Most favorable of staggared conformations






31. 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






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






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






34. 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-






35. Carbon carbon triple bonds. Suffix-yne.






36. Transfer of electrions from one atome to another






37. Alphabetical order of alkane rxn






38. 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






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






40. Common name for ethyne






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






42. N - l - ml - ms






43. When boat flips






44. Formed by mixing different types of orbitals






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






46. A = observed rotation / concentration * length






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






48. O3






49. A sigma bond and two pi bonds






50. 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.
