Anyone know the Lewis dot structure

[Dee4j]

for SiC  (silicon carbide)

I've sent my son moving on on his homework, but can't find the answer anywhere.

their valences each have 4 electrons and it can't have a quadruple bond??? (per my son)

I'm not going to able to sleep until I get this answer

[Dee4j]

still not sleeping....No chemistry whizzes out there?

Try going to bed.....the chemistry is pretty much automatic.... :sombraro:

Holy Smokes,

You are asking questions outside my realm of understanding.

You know I used to know the Lewis dot structure by heart.... :rolleyes:

Has this to do with Lewis acid?

What would we do without the internet  :eyecrazy:
this is one of many hits I got Lewis Dot
Hope it helps

This is my best guess.  It's been a while since I took organic chemistry.

.Si-C.
 .   .

They single bond to each other, with the other three electrons free to bond to other atoms.  Silicon carbide creates a crystalline structure as it builds.

Thanks I will run it by him, I'm not sure tho it's not following the Octet rule

hopefully he asked his teacher today and I will let you know what it is...

yes I have found a bunch of stuff on how to do it. He understands that part. the problem is each has 4 valence electrons. The Octet rule says there must be 8 total a single bond leaves you with 7 a double bond & triple bond leave you with too many. what would work is a quadruple bond which doesn't exist

hey you work at  HS you can ask the Chem teacher???

I believe it forms a crystal structure so that each silicon atom is surrounded by carbon atoms and vice versa. Each atom would have a double bond. Say...

Si:C:Si:C:Si
.. .. .. .. ..
C:Si:C:Si:C
.. .. .. .. ..
Si:C:Si:C:Si

It has been a few years since college Chemistry but I believe this is correct.

Si:C:Si:C:Si
.. .. .. .. ..
C:Si:C:Si:C
.. .. .. .. ..
Si:C:Si:C:Si

I believe it is either that, or, alternatively, a double bond with 2 pairs of electrons on each component.

..  ..
Si=C
..  ..

The "equal sign" is a double bond represent two pairs of 2 electrons.

Just as I thought...
