Hello,
Throughout the exams in salters and I presume normal chemistry there is plenty of questions where they ask to define/explain what something is.

These are easy questions where marks can be won by simply memorising things without any understanding.

So i thought this thread could be for anyone who finds a define/ explain question and wants to post it.
For example, "Explain what an addition polymer is" is a question that can be answered by defining each element. These are the sorts of questions I am talking about.

The units F332 and F335 have a bit of overlap so content from both exams can be included in this thread.
Cheers in advance to anyone who takes part.

To start of with.

"What is a chromophore group?"

- A chromophore group is a compound that contains unsaturated functional groups such as C=O, C=C or -N=N- directly connected to an extended system of delocalised electrons

This is a great thread, im doing the other syllabus ,it would have been great to ask/answers q etc

Explain the term electronegativity

Electronegativity is the extent to which the atoms of an element attract the electrons in a covalent bond.
The italics and bold bits are the seperate two marks

That was a simple easy 2 marker in F335 jan 12

it also the part of the molecule which gives its colour
