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






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






3. Refers to the =CH2 group






4. Highest energy no separation. or 120 separation.






5. Zn/h or CH3/s with ozonolysis






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






7. If reagent has a bunch of oxygen






8. Not solvated






9. F - CL - Br - I






10. One s and two p 120 degree apart






11. Same molecular formula but different structure






12. Carbon double bonded to an oxygen






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






14. 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






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






16. Diol with hydroxyl group on same carbon






17. Diols with hydroxyl group on adjacent carbon






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






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






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






21. Is bonded to only one other carbon atom






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






24. Monosubstituted ethylene






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






26. What is produced when o3 with lialh4 or nabh4






27. Sharing of electron between atoms






28. A radical transfers a hydrogen atom to another radical and makes an alkane and alkene






29. Rotations cancel each other out therefore no optical activity






30. 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.






31. Transfer of electrions from one atome to another






32. Name for propanal






33. Functionality is specified by alkoxy- prefix. ROR






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






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






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






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






38. O3






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






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






41. Goal is to produce most stable carbocation

42. Name for mathanal






43. 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.






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






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






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






47. When boat flips






48. N - l - ml - ms






49. 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-






50. Common name for ethyne
