Do we need to know about sigma/pi bonds in AQA A-Level Chemistry?

Hi guys, I just wanted to enquire about whether we need to know sigma and pi bonds for AQA. I know some other exam boards do but my teachers have never mentioned it. However, some websites and tutors talk about sigma and pi bonds for AQA so just wanted to know if its on the spec. Thankssss xx

I'm pretty sure you need to know the basics, yes.

cool, so by basics you mean their strength and where they are found/their structure, right?

I think you actually need to search for your specification on the board's website and look at the required content. I've just had a quick look on the AQA specification under 'physical chemistry' and I can't find any reference to sigma/pi bonds - so maybe you don't actually need to know about them after all.

The specification is here (but check that this is the right one for you)

Even if you don't need to know it, chemical bonds are the most fundamental part of chemistry and it can't hurt to know about them, there's not much that's difficult about them anyway. Sigma bonds are stronger and any time you see a double or triple bond you know there's at least one pi bond in there. A double bond is composed of 1 sigma + 1 pi. A triple bond is 1 sigma + 2 pi.

On the OCR A spec, it is in alkenes, so perhaps you were looking in the wrong place on the AQA spec.

But, like you said, it really should be up to the OP to be doing this basic research.

I just took my A Level Chemistry this year, and unless the specification has changed, you don't need to know anything about sigma/pi bonds in AQA A Level Chemistry. I mean, if it makes you feel more confident about your knowledge, then I guess you can look into them, but you don't need to know about them to answer the questions. (I got an A in AQA A Level Chemistry).

For AQA no, and if you're struggling to understand any of it then just don't bother learning it. You don't need it for the exam, it won't benefit your grade, and so has no purpose right now. If you want to pursue chemistry beyond A-level, probably best to learn it. If not, there's no point for AQA.

I got an A* in AQA A-level Chemistry in 2018, didn't know a thing about sigma/pi/antibonding/pi-pi back donation etc until 1st year degree chemistry.
