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. Sharing of electron between atoms






2. Common name for ethyne






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






4. One s and three p orbitals






5. One s and two p 120 degree apart






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






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






8. Di - tri - t - sec - n -






9. Carbon carbon triple bonds. Suffix-yne.






10. 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






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






12. If reagent has a bunch of oxygen






13. Steps of free radical substitution






14. Alphabetical order of alkane rxn






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






16. A = observed rotation / concentration * length






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






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






19. Highest energy no separation. or 120 separation.






20. Not solvated






21. Monosubstituted ethylene






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






23. Kmno4






24. M - chloroperoxybenzoic acid






25. Name for mathanal






26. Is bonded to only one other carbon atom






27. Combustion reaction occurs through a radical process






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






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






30. Functionality is specified by alkoxy- prefix. ROR






31. 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.






32. Propylenes attached to a backbone at the C-3 position. Meaning the double bond at end of the chain and single bonded carbon at rest






33. Compounds with halogen






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






35. Most favorable of staggared conformations






36. Diol with hydroxyl group on same carbon






37. Carbon double bonded to an oxygen






38. Charged - need electrons






39. 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.






40. O3






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






42. 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






43. Formed by mixing different types of orbitals






44. Transfer of electrions from one atome to another






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






46. Iso - neo - cyclo






47. Methyl are 60 degrees apart. kinda stable






48. Diols with hydroxyl group on adjacent carbon






49. Fast process. double bond is nucleophile and attack x2. make cyclic halonium ion with either br or cl. and make dihalo trans






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