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. Steps of free radical substitution






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






3. Diols with hydroxyl group on adjacent carbon






4. Name for propanal






5. Highest energy no separation. or 120 separation.






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






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






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






9. Rotations cancel each other out therefore no optical activity






10. Sharing of electron between atoms






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






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






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






14. Kmno4






15. Carbon carbon triple bonds. Suffix-yne.






16. When boat flips






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






18. 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-






19. Combustion reaction occurs through a radical process






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






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






22. 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






23. Goal is to produce most stable carbocation

24. Name for ethanal






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






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






27. Is bonded to only one other carbon atom






28. Di - tri - t - sec - n -






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






30. Refers to the =CH2 group






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






32. Name for mathanal






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






34. Same molecular formula but different structure






35. Y = position of double bond - x is position of triple bond - root is the prefix representing the length of the principal carbon chain






36. Object that is not superimposable upon mirror image






37. Iso - neo - cyclo






38. A molecule with an internal plane of symmetry






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






41. 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.






42. Lowest priority group projects into the page






43. Most favorable of staggared conformations






44. Formed by mixing different types of orbitals






45. A sigma bond and two pi bonds






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






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






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






49. What is produced when o3 with lialh4 or nabh4






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