Electron acceptor / donor

Postby Reina Robles 2B » Tue Nov 26, 2019 10:09 am

So I know Lewis acids are electron acceptors, and Lewis bases are electron donors. But how do you know whether a molecule accepts or donates an electron?

Normally, electron acceptors (Lewis acids) are positively charged, and electron donors (Lewis bases) are negatively charged (this may not be the case all the time). For me, drawing the Lewis structure helps determine which species has lone pairs of electrons, which helps to determine the Lewis base.

Thank you so much!
