Is a Double Bond Required in the Lewis Structure of SnCl2?

[blue bloom]

a question in Lewis structure?

I know that Lewis structure is so easy to discuss ..but I have this compound :
SnCl2
when I drew the Lewis structure of its , I had to make Double bond between the Cl & Sn
..but a teacher told me once that when the Cl is not the central atom it can just make a single bond ..
so that it looks so weird for me !
Is it an abnormal case -like PO4- ?
what is the real structure ?

 

[alxm]

One free electron pair on tin, single bonds to the chlorines which have full octets.
(The octet rule doesn't apply to tin.)

(The octet rule doesn't apply to tin.)

More precisely, octet rule works mainly for the second period of periodic table.

in my book,i found that the octet rule works only with the elements C,N,O,F.
? i don't get it ??

Don't worry - there is no obvious border where it works, where it doesn't. Octet rule and Lewis structures are only a simplification of the reality, no wonder they regularly fail.

actually ..in MY book they are talking about the octet rule as a main rule
I mean.. it works with all the compounds except some odd of them
& I still do not know the structure of (SnCl2):shy:

Let me guess - that's your first year of chemistry?

the system of my education is not like yours ..
but you can consider that is my 2nd year (with) chemistry
the first year -most of it- was an endless equations
anyway it is ok after all -for me at least!-
