MCAT Organic Chemistry

Subjects : mcat, science
Instructions:
  • Answer 50 questions in 30 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. Not solvated






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






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






4. Functionality is specified by alkoxy- prefix. ROR






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






6. Highest energy no separation. or 120 separation.






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






8. One s and two p 120 degree apart






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






10. 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.






11. Formed by mixing different types of orbitals






12. Sharing of electron between atoms






13. Diols with hydroxyl group on adjacent carbon






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






15. 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.






16. Steps of free radical substitution






17. 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






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






19. When bond angles deviate from ideal values






20. Zn/h or CH3/s with ozonolysis






21. M - chloroperoxybenzoic acid






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


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






24. 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-






25. Iso - neo - cyclo






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






27. 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






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






29. Monosubstituted ethylene






30. Compounds with halogen






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






32. Object that is not superimposable upon mirror image






33. Refers to the =CH2 group






34. Is bonded to only one other carbon atom






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






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






37. Carbon carbon triple bonds. Suffix-yne.






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






39. Name for ethanal






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






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






42. Transfer of electrions from one atome to another






43. Two hydroxyl groups






44. Combustion reaction occurs through a radical process






45. 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






46. What are the best leaving groups?






47. Same molecular formula but different structure






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






49. Goal is to produce most stable carbocation


50. A molecule with an internal plane of symmetry
