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






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






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






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






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






6. Name for mathanal






7. Compounds with halogen






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






9. Is bonded to only one other carbon atom






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






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






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






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






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






15. Alphabetical order of alkane rxn






16. Common name for ethyne






17. Name for propanal






18. When boat flips






19. 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






20. F - CL - Br - I






21. One s and three p orbitals






22. Methyl are 60 degrees apart. kinda stable






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






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






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






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






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






28. Not solvated






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






30. Name for ethanal






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






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






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






34. When bond angles deviate from ideal values






35. In which one or morehydrogen atoms are replaced with a halogen atom. via free radical substitution






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






37. Carbon double bonded to an oxygen






38. Kmno4






39. 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.






40. Di - tri - t - sec - n -






41. A molecule with an internal plane of symmetry






42. Hydrocarbon with one or more carbon carbon triple bond






43. If reagent has a bunch of oxygen






44. When a molecular orbital is formed head to head or tail to tail. all single bonds are tehese.






45. Diol with hydroxyl group on same carbon






46. What are the best leaving groups?






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






48. When two atomic orbitals combine. obtained mathematically by adding or subtracting wave functions. if sings are the same - make bonding - if different - less stable antibonding.






49. Monosubstituted ethylene






50. Lowest priority group projects into the page
