$A$ biodegradable polyamide can be made from:

Arrange the following polymers in increasing order of their intermolecular forces.
$(i)$ Nylon $6,6$,Buna$-S$,Polythene.
$(ii)$ Nylon $6$,Neoprene,Polyvinyl chloride.

Match the following:

List-$I$ (Use)	List-$II$ (Substance)
$A$. Electrodes in batteries	$II$. Polyacetylene
$B$. Welding of metals	$III$. Oxyacetylene
$C$. Toys	$I$. Polypropylene

The correct answer is

Which one of the following is a biodegradable polymer?

Which one of the following is a polyamide polymer?

In which of the following pairs is the polymer correctly matched with the intermolecular forces present in them?

$A$. Neoprene --- Weak intermolecular forces	$B$. Terylene --- Hydrogen bonding
$C$. Polystyrene --- Very weak intermolecular forces	$D$. Polythene --- Hydrogen bonding
