Q. 4.1B

Postby Chloe Likwong 2K » Sat Nov 10, 2018 11:36 pm

I just wanted to verify the answer for question 4.1B.

Is the reason why a linear molecule "may have lone pairs" is that said molecule can have lone pairs of electrons as long as the ends have the same amount of pairs? Or is it completely dependent on the central atom having a lone pair or not?

Only the lone pairs around the central atom will matter. While a linear molecule may have lone pairs, not all molecules with 2 bonding pairs and a certain number lone pairs will be linear. For instance, in H2O the central atom oxygen will have 2 lone pairs and thus the molecular geometry will be bent and not linear. Molecules with 2 bonding pairs and 3 and 4 lone pairs will be linear thought. This link may be helpful: https://www.chemmybear.com/shapes.html
