# Polymerisation. watch

1. I thought that equation for every addition polymerisation is like this(for example):

As n=1, so the moles of polymer can never be less than 1.

This is a three-statement multiple completion item. The mark scheme says that only 2nd and 3rd option are correct. Is my equation wrong, then?

No, your equation is correct, but n is a large number and not in this case representative of the number of moles, rather the number of reacting particles ...

Poly = many
Mer = parts

... if n = 1 there has been no addition, no reaction and no'product'

It is not a polymer, in fact it is not possible without hydrogen adding onto the ends.

Hmm, then is the 1st option incorrect for the following reason? If one mole of a monomer reacts, 6 x 1023 particles of monomer add up to form a polymer(more particles) with less number of moles. So the moles of polymer will always be less than that of monomer...
