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. Highest energy no separation. or 120 separation.






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






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






4. Zn/h or CH3/s with ozonolysis






5. Refers to the =CH2 group






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






7. A = observed rotation / concentration * length






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






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






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






11. When boat flips






12. Name for mathanal






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






14. Di - tri - t - sec - n -






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






16. Combustion reaction occurs through a radical process






17. Steps of free radical substitution






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






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






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






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






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






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






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






26. Goal is to produce most stable carbocation

27. Carbon double bonded to an oxygen






28. Formed by mixing different types of orbitals






29. 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






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






31. Charged - need electrons






32. Functionality is specified by alkoxy- prefix. ROR






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






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






35. Compounds with halogen






36. Not solvated






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






38. A molecule with an internal plane of symmetry






39. If reagent has a bunch of oxygen






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






41. Common name for ethyne






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

43. Kmno4






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






45. Sharing of electron between atoms






46. Most favorable of staggared conformations






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






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






49. Iso - neo - cyclo






50. Diol with hydroxyl group on same carbon
