COS,
可唔可以將C=O=S寫成O=C=S?
定係有咩規律ge呢?
仲有structural formula of organic molecule, 有咩排序規則要注意?

✔ 最佳答案
It is O=C=Ssince O and S has 6 outermost electron
they need 2 more electron,
so then need one double bond or 2 single bond
for C, C has 4 outermost electron
it needs 4 more elctron,
it needs a total 4 bonding
So, it is O=C=S

The structural formula is S=C=O , not the others . COS is called Carbonyl Sulfide .

不可以寫成C=O=S , 因為O cannot form 4 bonds ,2 with C & 2 with S .
