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. Compounds with halogen






2. Hydrocarbon with one or more carbon carbon triple bond






3. Is bonded to only one other carbon atom






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






5. 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






6. Object that is not superimposable upon mirror image






7. Kmno4






8. Same molecular formula but different structure






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






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






11. Diols with hydroxyl group on adjacent carbon






12. What are the best leaving groups?






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






14. O3






15. Carbon double bonded to an oxygen






16. 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.






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






18. Steps of free radical substitution






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






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






21. Name for ethanal






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. Sharing of electron between atoms






24. 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






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






26. M - chloroperoxybenzoic acid






27. 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.






28. If reagent has a bunch of oxygen






29. Goal is to produce most stable carbocation

30. 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






31. Charged - need electrons






32. One s and two p 120 degree apart






33. A sigma bond and two pi bonds






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






35. Highest energy no separation. or 120 separation.






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






37. Not solvated






38. Methyl are 60 degrees apart. kinda stable






39. 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






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






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






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






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






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






45. Combustion reaction occurs through a radical process






46. Three different substitutents often have plane of symmetry. and rotation of 180 will allow molecule to be superimposed on mirror image






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






48. Name for mathanal






49. Iso - neo - cyclo






50. One s and three p orbitals
