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






2. Goal is to produce most stable carbocation

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






4. What is produced when o3 with lialh4 or nabh4






5. Object that is not superimposable upon mirror image






6. Name for ethanal






7. Hydrocarbon with one or more carbon carbon triple bond






8. Sharing of electron between atoms






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






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






11. 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.






12. Kmno4






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. Compounds with halogen






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






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






17. 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






18. One s and three p orbitals






19. A sigma bond and two pi bonds






20. F - CL - Br - I






21. When bond angles deviate from ideal values






22. N - l - ml - ms






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






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






25. Name for mathanal






26. Carbon double bonded to an oxygen






27. One s and two p 120 degree apart






28. When boat flips






29. Rotations cancel each other out therefore no optical activity






30. 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.






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






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






33. Not solvated






34. Iso - neo - cyclo






35. 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






36. Is bonded to only one other carbon atom






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






38. Name for propanal






39. Transfer of electrions from one atome to another






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






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






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






43. Diols with hydroxyl group on adjacent carbon






44. Diol with hydroxyl group on same carbon






45. Charged - need electrons






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






47. A = observed rotation / concentration * length






48. 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






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






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