acid v. base?

Postby Doris Cho 1D » Sat Nov 30, 2019 6:52 pm

How can you tell if something is a lewis acid or base based on the lewis structure?

Lewis bases typically contain lone pairs and often are negatively charged. Lewis acids are often positively charged and can accept lone pairs. Your notes should contain a list of characteristics

Lewis bases are more likely to accept H+ ions to make a basic solution, whereas lewis acids are more likely to accept OH- ions to make a neutral solution

Lewis bases should have a lone pair to donate while lewis acids are usually positively charged and therefore able to accept an electron pair.

Lewis acids accept an electron pair while Lewis bases contain electron pairs.

Lewis acids also typically have a hydrogen ion in front of the name of the molecule. For instance, HCl or HBr.

doesnt it depend on whether or not they are giving up or accepting a proton

Lewis bases will typically contain the lone pair to donate to the Lewis acid

You can distinguish them by figuring out which one accepts proton and which one donates proton.

Lewis bases are positively charged. Lewis acids are negatively charged and usually have a lone pair.

Lewis bases usually have a lone pair so that it has electrons to donate while Lewis acids usually have a positive charge attached to them, meaning that they will likely accept an electron pair.

The Lewis structure of a Lewis acid typically has a positive charge, making them capable and likely to accept an electron pair. Lewis bases typically have a lone pair available to donate.

the lewis structure that has a lone pair ready to donate would be a base, while the lewis structure carrying a positive charge is an acid.

Lewis acids can accept electrons because they have an empty orbital. So, to identify a Lewis acid, just look for an incomplete octet. Lewis bases have to have a lone pair (though not every structure with a lone pair is a Lewis base, obviously).

If the molecule has lone pairs it is more than likely a lewis base because it can donate those electrons and if a molecule has a positive charge it is more likely to accept electrons therefore it is a lewis acid.

Lewis acids will donate electrons and Lewis bases will accept electrons
