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






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






3. Name for mathanal






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






5. Compounds with halogen






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






7. Kmno4






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






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






10. When boat flips






11. Di - tri - t - sec - n -






12. Refers to the =CH2 group






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






14. Formed by mixing different types of orbitals






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






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






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






18. 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.






19. 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






20. Methyl are 60 degrees apart. kinda stable






21. 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-






22. 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






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






24. Palladium or barium sulfate (BaSO4) with quinoline. occur on metal surface - make cis.

25. Hydrocarbon with one or more carbon carbon triple bond






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






27. Highest energy no separation. or 120 separation.






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






29. 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






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






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






32. Name for ethanal






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






34. 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






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






36. Functionality is specified by alkoxy- prefix. ROR






37. 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.






38. When bond angles deviate from ideal values






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






40. O3






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






42. Name for propanal






43. Steps of free radical substitution






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






45. Diols with hydroxyl group on adjacent carbon






46. Monosubstituted ethylene






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






48. What is produced when o3 with lialh4 or nabh4






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






50. Alphabetical order of alkane rxn
