GCSE Chemistry - What is a Polymer? Polymers / Monomers / Their Properties Explained #23

Everything you need to know about polymers!
Polymers are large molecules made up of lots of repeating units called monomers. This video covers: how to identify them, how to draw them, and their properties.

Why do we use a (Cl - Cl) “-“ notation for covalent bonds but not a notation for ionic bonds? Like instead of NaCl it’d be: (Na+-Cl)?

[@durjam3734]

Have you done one on polymer condensation and addition?

Not yet i'm afraid, we're working our way through the course in order, so that will come a bit later!

Would using square brackets instead of the curved ones be considered as a mistake on the igcse 0620 chem exam??

[@GilIsaacson]

Is another reason why a polymers boiling/melting point is higher than that oof simple molecular forces to do with the size of those Inter molecular forces? (as well as how many imf there are )

[@WEEBWHOSELLSWEED]

Hey Cognito
You might have noticed me a lot in your comments now, it's a fact that I am using your videos to make my own notes, can you please exaggerate the types of additional and condensation polymers.
If not a video, comment would work too.
I like your video, great work.

PLEASE CAN U MAKE A VIDEO ON WATER CRYSTALLISATION!!!!!!!!!!!!!!!!!!!!!

[@didyouforgetalready]

Theres save my exams notes on it. If youre taking IGCSE it’s not a lengthy topic which requires video explanation but in general they are just a compound that’s presented in hydrated salts. If you want to test for water of crystallisation you can use cobalt chloride which turns from blue to pink if hydrated and copper sulphate which is white in anhydrous and light blue in hydrous.
