when doing the electrophilic addition with water, what is needed for it to happen

an acid catalyst

when doing the first step of electrophilic addition mechanism with water, what is the initial electrophile

the H⁺ from the acid catalyst.

NOT a H from water

are (addition) polymers reactive?

no, they are not reactive

polymers are used to make everyday _________ products such as ________

plastic products such as shopping bags

what is the polymer that makes shopping bags?

poly(ethene)

are addition polymers biodegradable? why/why not?

no, they are not biodegradable

• because they have unreactive bonds and the bonds are non polar
