CH4, which is the most reduced form of carbon.
That chemical is ethylene gas.
The chemical formula for ethylene glycol is C2H6O2.
ethylene glycol
The chemical formula for ethene (an alkene) is C2H4.
H2O is 2 hydrogens plus 1 oxygen and that makes the chemical formula for water.

ethylene
Frequently is used the ethylene oxide.
The chemical equation is:C2H4 + Br2 = C2H4Br2
Cl2
To determine the grams of ethylene needed to react with 0.0126 mole of water, you need to use the balanced chemical equation for the reaction between ethylene and water. Once you have the balanced equation, use the molar ratio between ethylene and water to convert moles of water to moles of ethylene. Then, use the molar mass of ethylene to convert moles of ethylene to grams of ethylene.
