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. A radical transfers a hydrogen atom to another radical and makes an alkane and alkene






2. 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






3. N - l - ml - ms






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






5. Not solvated






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

7. O3






8. Is bonded to only one other carbon atom






9. One s and two p 120 degree apart






10. Carbon double bonded to an oxygen






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






12. 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






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






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






15. Di - tri - t - sec - n -






16. 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






17. Common name for ethyne






18. Kmno4






19. 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






20. 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.






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






22. Iso - neo - cyclo






23. Highest energy no separation. or 120 separation.






24. Most favorable of staggared conformations






25. Two hydroxyl groups






26. Name for ethanal






27. Same molecular formula but different structure






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






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






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






31. When boat flips






32. A = observed rotation / concentration * length






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






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






35. Lowest priority group projects into the page






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






37. 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






38. Differ in position of substitutents attached to a double bond or cycloalkane. Cis or trans or e or z






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






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






42. Diol with hydroxyl group on same carbon






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






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






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






46. Alphabetical order of alkane rxn






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






48. What are the best leaving groups?






49. Combustion reaction occurs through a radical process






50. If reagent has a bunch of oxygen
