Bond Angles

Postby Michael Du 1E » Sat Nov 16, 2019 10:27 pm

I remember Professor Lavelle mentioning how there could be two tetrahedrals of two different molecules (same central atom but different outside atoms attached to it) and that one of them would have a slightly lower bond angle due to the atom's size or electronegativity from what I recall. How would the electronegativity or size of an atom slightly affect the bond angle? thank you!

I believe that higher electronegativity/size will cause more electron-electron repulsion thus decreasing certain bond angles.

The size of an atom can affect the molecule by throwing off the distribution of electrons. For example, a bigger molecule with more electrons will repel the other bonding groups, creating a larger bond angle. Electronegativity will attract electrons to certain atoms. With really electronegative elements, it might decrease the bond angle of surrounding bonding groups. Hope this helped!
