Which polymer structure should be used if a strong and heat - resistant adhesive is required? 1. Linear

2. Branched

3. Networked

4 . Cross - linked

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
