Bond Variations

Postby Stevin1H » Thu Nov 22, 2018 1:09 pm

How is the strength of bonds affected by the presence of lone pairs? Is the strength of a bond stronger or weaker with or without the presence of lone pairs?

Lone pairs weaken the strength of a bond because of electron repulsion - the lone pair electrons of an atom will repel the bonded electrons and such electron-electron repulsion will reduce the overall bond's strength.

Lone pairs on neighboring atoms repel each other and weakens the bond.

Do lone pairs also affect the way the model is oriented? Because of the repulsion?

Yes, they do because lone pairs repel the bonding pairs, which changes the orientation. The best example is how in a linear molecule, if you add a lone-pair, the molecule becomes bent.
