How many equivalent Lewis structures are necessary to describe the bonding in SeBr2O?

SeBr2O only has one lewis structure. you can fill all of the lone pairs without having to use a double bond (double bonds are why there are equivalent lewis structures)


How many bonding and non-bonding electrons pairs are found in the BF3 molecules?

There are three bonding pairs of electrons in BF3. There are 0 nonbinding pairs, but BF3 can accept two more electrons to give it a complete octet


In a molecule of methane carbon (having four valence electrons) binds to four hydrogen atoms. How many lone pairs of electrons will be represented in the Lewis structure of methane?

NONE!!! Each bonding electron in carbon is paired with the bonding electron in each of the four hydrogens. So there are no lone pairs.
