bent v. angular

Postby Maya Beal Dis 1D » Tue Nov 19, 2019 2:47 pm

What qualifies as the shape bent and what is angular? Are they the same thing?

I think in lecture Lavelle referred to a central atom with two bonding domains and two lone pairs as bent, but in the textbook they've been using angular as the shape name.

If there is a central atom with two bonding regions and one lone pair what shape is it?

Bent and angular are the same and can be used interchangeably! It's all up to personal preference whether to call the shape bent or angular. 2 bonded and 1 lone pair is bent, and 2 bonded and 2 lone pairs is also bent.

The two classifications are synonymous, the terms mean exactly the same thing. When a central atom has two bonding regions and one lone pair its shape is bent/angular.

Bent and angular mean the same thing. There are also several names for other structures, such as seesaw (disphenoidal).

bent and angular are just synonyms for each other

Bent and angular refer to the same shape with VSEPR formulas AX2E or AX2E2.

Bent and angular refer to the same type of shape. Either works when naming AX2E and AX2E2 molecules.

Bent and angular are interchangeable terms for the same type of shape. Both work when naming AX2E and AX2E2 molecules. Additionally, AX2E and AX2E2 are both bent/angular shape but have different angles depending on how many electron pairs they have. AX2E has one electron pair and the bond angles are >120 degrees , but for AX2E2 there are two electron pairs so the repulsion between the bonds is greater so the bond angles are smaller being >109.5 degrees.

When the VSEPR formula is AX2E3 or AX2E4, remember that their shapes will be linear (not bent or angular) and they both will have a bond angle of 180 degrees.

Bent and angular are same names of the same shape. This molecular geometry can happen when there is one central atom with two bonding regions and one or two lone pairs. The only difference is that their bond angles are different.

But which one is more preferable to say? Bent or angular? Because I mostly see bent.

To be sure it is best to use bent because that is what Lavelle said and he is the ultimate decider. They are the same thing though and at the end of the day is shouldn't matter but like I said to be safe just mention it as bent if that is what he refers it as.

Bent and angular are the same thing and produce the same shape. However, be careful of the bond angles because are two different bond angles depending on how many electron density fields there are.

Bent and angular are interchangeable. Whichever term you prefer, you may use.

Bent and angular mean the same thing! You can use either one, I've personally seen bent the most frequently.

From what I remembered from high school, bent and angular are the same thing where you have two bond pairs and two lone pairs on an atom.

Does any angular measurement aside from 180 mean the molecule has bent/ angular character?

Does anyone know if Dr. Lavelle will be using bent and angular interchangeably or if only one will be used on the midterm/final exam? I understand that they're the same thing, but I would like to know which one we should get more used to using if possible.

I think both will be fine for the midterm.

Bent and angular are the same thing and produce the same shape so I think we will not have to worry too much about it for the midterm.

Both mean the same thing. My old chemistry teacher preferred bent, but I think Dr. Lavelle will accept either. I would make sure that you know that they mean the same thing in case one versus the other is used on the exam. For example, if one question asks about bent, while another question asks about angular, make sure you know that both questions are asking for the same thing.
