Do lone pairs repel more?

Postby Kellylin_4D » Wed Nov 13, 2019 6:28 pm

I'm not sure if I heard correctly during lecture that lone pairs repel more in VSEPR. If that is true, why is that so?

Yes, 2 lone electrons will create a balloon of repulsion and push the bonded electrons away from them, because they take up more space compared to bonded electrons.

Yes! Lone pairs also have a stronger degree of repulsion since there's only one positive force that counteracts the energy of a lone pair, namely the nucleus of the atom to which the lone pair belongs to while bonded pairs have 2 positive nuclei in between them which act as 2 positive forces that counteract their negative charge.

A lone electron pair will repel its surroundings more than a bonded electron would because its negative charge isn't being distributed/shared unlike the bonded pair, thus its negative charge and repulsion is more concentrated/stronger.
