Bond Angles

[kristinalaudis3e]

For a lewis structure with 3 bonds and one lone pair have a bond angle closer to 106 (from lecture) or will it have a bond angle that is just less than that of a tetrahedral (109.5)?

I think the exact number depends on the properties of the compound, but in general, the number is less than 109.5º

What I learned in ap chem in hs is that each lone pair reduces the bond angle by 2.5. So one lone pair in tetrahedral would make the bond go from 109.5 to 107, which is p close to 106.

[Kelly Tran 1J]

The bond angle would be less than 109.5 due to the tetrahedral arrangement. The exact value of the bond angles depends on the atoms being bonded.

You should take into account that lone pairs can cause bond angles to decrease.

[Ruth Rosales 3D]

I normally say it is 106 because I figure that it is safer to use what they give us in class, however, I do see how this value could be affected by the properties of the compound as other people have said.

The bond angle for AX3E depends on the molecule specifically but they are always less than 109.5 due to electron repulsion from the lone pair.

For bond angles, I know some is a little less than a number, for example <109.5, does anyone know why?

[Aria Movassaghi 1A]

the bond angle is less than 109.5

[JohnathanH_1H]

Since the molecule is tetrahedral the bond angles will be less than 109.5 degrees, the exact degrees varies due to which elements are involved.

[Isabella Perez Dis3L]

it will have a bond angle that is just less than 109.5

[705573518]

When we know a bond angle is for example <109.5, do we need to specify how much smaller or is <109.5 a sufficient answer?

[Hailey Jeon]

It will be less than 109.5 degrees since the electron density of lone pairs are higher than of the bonds.
