Are we supposed to know how exactly the lewis theory of acids and bases works? (1 Viewer)

[SB257426]

Just wanna know if we need to fully understand the lewis theory, like knowing how the electron pair transfer and that sort works. Because when I was learning this a few months ago I recall my teacher saying that we don't need to know how lewis theory works.... we just need to know the definition. But im doing trial revision and a lot of websites I have been to mention the coordinate covalent bond (is coordinate covalent bond even in the course)?
Cheers

what i was told that we don't need to know lewis theory we only should know Lavoisier, humphrey-davis, arrhenius and bronsted-lowry
but maybe don't take my advice, my teacher's been wrong many times

No you don’t have to understand it, but you should understand why it was needed (the flaws in the Brønsted-Lowry theory)

Just mention BF3 as an acid that isn’t a proton donor that’s literally it

Thanks man... Appreciate it

It is also good to remember not only BF₃ is a Lewis acid, but also Al³⁺ and Fe³⁺ are examples of a fairly strong Lewis acids, and pH of FeCl₃(aq) is quite low. Students have been asked in the past to explain the effect of various ions on pH of water. FeCl₃ is a cheap and popular additive to swimming pool water to lower the pH.
The coordinate covalent bond was examinable in the older pre-2017 syllabus so you will find test questions doing the rounds that belong to the older syllabus.
