39Chlorine on standing separates to HCl and HOCl, the latter of which causes the bleaching action(because it releases nascent oxygen). It bleaches only organic matter...lead pencil is not organic?
11may be that carbon cannot be oxidised by chlorine ..... maybe because of its inertness....
1LOL... its' clear that Pritish has grasped NCERT word-by-word.
There was one more line beneath it.
Vegetable Oil + O --> Vegetable Ghee.
As it is said, I suppose it is for organic compounds only.
