Composition of a Bond

Postby Kristina Nguyen 1C » Fri Dec 08, 2017 10:10 pm

Would the composition of the OH bond in HCOOH be made up of a sigma(H1s, O2s)? Thanks!

The composition of the OH bond would be sigma(H 1s, O 2sp^3). The oxygen has 4 areas of electron density (two single bonds and two lone pairs), and that is why the composition of the OH bond includes "2sp^3".

Oh yeah I totally overlooked the lone pairs, thanks!

When we write the composition of bonds for Carbon, why is it that we write a 2 in front of the hybridization, like this C2sp^2?

the 2 is for the row number

Does anyone know why the pi bond is often (O 2p, O 2p) for let's say a double bond between two O atoms....and not (O 2sp^2, O 2sp^2)
