Identify the products and reaction conditions for the conversion of ethanol and ethene, and identify the polymer formed from ethene.

Here are the solutions to the questions:

a) The compound shown above that is a salt is Sodium ethanoate.

b)

i) To convert ethanol to ethene, the reagent used is concentrated sulfuric acid (or aluminium oxide) with heating.

ii) To convert ethanol to ethyl ethanoate, the reagent used is ethanoic acid (with concentrated sulfuric acid as a catalyst).

c)

i) The reaction conditions necessary to convert ethene to ethane are: hydrogen gas, nickel catalyst, and a temperature of 150°C.

ii) The equation for the reaction is:

$$\text{C}_2\text{H}_4(g) + \text{H}_2(g) \xrightarrow{\text{Ni catalyst, } 150^\circ\text{C}} \text{C}_2\text{H}_6(g)$$

d) The other product obtained when sodium hydroxide is reacted with ethyl ethanoate is ethanol.

e)

i) The type of reaction that occurs when ethanol is converted to ethanoic acid is oxidation.

ii) The type of reaction that occurs when ethene is converted to ethane is addition (specifically, hydrogenation).

f)
The polymer formed from ethene is poly(ethene) (or polyethylene).
The polymerisation process is addition polymerisation.
The conditions for the polymerisation process are: high temperature (e.g., 200°C), high pressure (e.g., 2000 atm), and a catalyst (e.g., oxygen or peroxide initiator).
