Question

The polymerisation of ethylene ti linear polyethylene is represent by nch2= ch2 give (-ch2-ch2-)n calculate polymerisation of ethylene per mole

Answer 1

Delta H ( polymerization ) = Δ H (C = C) − 2 Δ H (C−C) = 590 – 2 ( 331 ) = − 72 kilo Joules per mol .

In the polymerization of ethene, one mole of ethene breaks which means 1 C=C twofold bond breaks down and the 2 groups of CH2 – are connected with C – C single bonds along these lines framing three single bonds. In any case, in the entire unit of polymer, number of single C – C bonds framed per mole of ethylene is two.
