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. One s and three p orbitals






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






3. 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.






4. Common name for ethyne






5. Monosubstituted ethylene






6. M - chloroperoxybenzoic acid






7. Functionality is specified by alkoxy- prefix. ROR






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






9. Refers to the =CH2 group






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






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






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






13. A sigma bond and two pi bonds






14. F - CL - Br - I






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






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






17. Sharing of electron between atoms






18. 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.






19. What is produced when o3 with lialh4 or nabh4






20. Steps of free radical substitution






21. Is bonded to only one other carbon atom






22. Transfer of electrions from one atome to another






23. O3






24. 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






25. N - l - ml - ms






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






27. When boat flips






28. 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






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






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






31. 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






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






33. Rotations cancel each other out therefore no optical activity






34. Same molecular formula but different structure






35. Methyl are 60 degrees apart. kinda stable






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






37. Two hydroxyl groups






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






39. Diols with hydroxyl group on adjacent carbon






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






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






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






43. A molecule with an internal plane of symmetry






44. Compounds with halogen






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






46. Not solvated






47. Formed by mixing different types of orbitals






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






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






50. A = observed rotation / concentration * length
