What functional group is present in petroleum ether? |

|
|
Structure of ether |
|
|
|
Structure of MTBE |

|
You are told that the salt of an organic acid or base has much different solubility properties that the parent acid or base. What are the differences and why is this? |
salts are polar and so is water, like dissolves like. |
|
|
Would a salt be more soluble in polar or apolar solvents? |
polar |
|

How can you experimentally tell which layer is the organic layer and which is the aqueous in a liquid-liquid extraction? You cannot always base this on knowing the relative densities of the two liquids. Why can’t you do this? |
You can take a few drops of the layer in question and drop them into a test tube containing water. If the drops form a new layer then the layer in question is organic. If no new layer is formed then the drops are aqueous.
If sufficient material is extracted from the aq phase to organ. phase or vice versa the relative densities of the two phases can change enough for them to exchange places. |

|
Which is more acidic, 3-nitrophenol or 2-nitrophenol and WHY? |
2-nitrophenol because of resonance/ inductive effects |
|
|
Things that increase acidity of H-A |
higher electronegativity of A increasing size of A resonance (stabilizing effect)
For Phenols: substituents on ortho or para position to OH electron withdrawing groups
