Name: 1. Draw the Lewis Dot diagram for the molecule AB2C. Element A has 4 valence electrons
and requires a full octet. Element B has 1 valence electron, but only gets 2 valence
electrons to have a full outer shell. Element C has 6 valence electrons and needs
to
have 8 valence electrons for a full octet.
Identify the chane name for the molecule

See attached picture and explanation.

Explanation:

Hello!

In this case, given the instruction on the molecule, we can infer that A is the central atom as it must have a full octet which is reached via one bond with each B atom. Moreover, via a double bond with C, both A and C are able to have the required full octet as shown on the attached picture.

For the name, it looks like the formaldehyde () which has two single-bonded hydrogen atoms and one double-bonded oxygen atom in order to have a full octet forth both carbon and oxygen.

Regards.
