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






2. 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






3. One s and three p orbitals






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






5. Refers to the =CH2 group






6. Steps of free radical substitution






7. 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






8. Transfer of electrions from one atome to another






9. Compounds with halogen






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






11. Zn/h or CH3/s with ozonolysis






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






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






14. 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.






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






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






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






18. Name for propanal






19. Functionality is specified by alkoxy- prefix. ROR






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






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






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






23. A sigma bond and two pi bonds






24. Highest energy no separation. or 120 separation.






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






26. Carbon carbon triple bonds. Suffix-yne.






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






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






29. Two hydroxyl groups






30. Most favorable of staggared conformations






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






32. Diols with hydroxyl group on adjacent carbon






33. 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-






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






35. A molecule with an internal plane of symmetry






36. N - l - ml - ms






37. Lowest priority group projects into the page






38. Is bonded to only one other carbon atom






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






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






41. Name for ethanal






42. If reagent has a bunch of oxygen






43. Iso - neo - cyclo






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






45. Monosubstituted ethylene






46. What is produced when o3 with lialh4 or nabh4






47. When bond angles deviate from ideal values






48. 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






49. Kmno4






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