|
|
Addition polymers formed from alkenes do not biodegrade
|
|
|
Condesation polymers may photodegrade
|
|
|
All condensation polymers biodegrade within a couple of years
|
|
|
None of the above
|
Detailed explanation-1: -These polymers do not yield any other product during formation. In this question we have to find the polymer which is not condensation polymer and neoprene is not condensation polymer. This means answer is option B that is Neoprene. So, the correct answer is “Option B”.
Detailed explanation-2: -Condensation polymers are broken down naturally by hydrolysis into their monomer units. They are therefore biodegradable and easier to dispose off than addition polymers.
Detailed explanation-3: -The main polymer chain is made from carbon atoms bonded by strong covalent bonds. There are, therefore no polar bonds in addition polymers. This makes the polyalkenes inert and non-biodegradable.
Detailed explanation-4: -HDPE is not a polymer. B: FALSE. Addition polymers are not polymers.
