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. Name for propanal






2. Kmno4






3. Lowest priority group projects into the page






4. 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






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






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






7. Carbon carbon triple bonds. Suffix-yne.






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






9. O3






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






11. Name for ethanal






12. Steps of free radical substitution






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






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






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






16. 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-






17. Refers to the =CH2 group






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






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






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






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






22. Compounds with halogen






23. Highest energy no separation. or 120 separation.






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






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






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






27. Diol with hydroxyl group on same carbon






28. Hydrocarbon with one or more carbon carbon triple bond






29. Same molecular formula but different structure






30. If reagent has a bunch of oxygen






31. One s and two p 120 degree apart






32. Transfer of electrions from one atome to another






33. Functionality is specified by alkoxy- prefix. ROR






34. 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






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






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






37. M - chloroperoxybenzoic acid






38. 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.






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






40. N - l - ml - ms






41. Two hydroxyl groups






42. 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






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






44. Formed by mixing different types of orbitals






45. Use the Greek root for the number of carbons followed by the ending - - ane






46. When boat flips






47. A = observed rotation / concentration * length






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






49. Methyl are 60 degrees apart. kinda stable






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