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






2. Combustion reaction occurs through a radical process






3. Charged - need electrons






4. Alphabetical order of alkane rxn






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






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. Electrons of pi bond are reactive and easily attacked by molecules that want e pair e.g. electrophiles.






8. Carbon double bonded to an oxygen






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






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






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






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






13. One s and three p orbitals






14. Sharing of electron between atoms






15. If reagent has a bunch of oxygen






16. 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.






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






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






19. Transfer of electrions from one atome to another






20. N - l - ml - ms






21. How many stereoisomers can a molecule have with n chiral centers






22. 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






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. Configuration in relation to another chiral molecule. use it to determine if a molecule is an enantiomer - diastereomer - etc






25. Rotations cancel each other out therefore no optical activity






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






27. 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.






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






29. Is bonded to only one other carbon atom






30. Contain carbon carbon double bonds. Use same root of alkane but end with 'ene'






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






32. A = observed rotation / concentration * length






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






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






35. Not solvated






36. Two hydroxyl groups






37. Name for ethanal






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






39. Lowest priority group projects into the page






40. Steps of free radical substitution






41. A molecule with an internal plane of symmetry






42. Monosubstituted ethylene






43. Kmno4






44. Describes the exact spatial arrangement of groups of atoms independent of other molecules.






45. Diol with hydroxyl group on same carbon






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






47. 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.






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






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






50. Name for propanal
