Which of the following statment is true?
SnCl4 is more stable than SnCl2
PbCl2 is more stable than PbCl4
GeCl4, is more stable than GeCl2
TICl3 is more stable than TICl
Microcosmic salt when heated strongly, a transparent bead is formed which is used in the identification of
ZnO
Al2O3
MgO

Chlorine is least reactive in
methyl chloride
ethyl chloride
vinyl chloride
allyl chloride
C.
vinyl chloride
The non-reactivity of chlorine atom in vinyl chloride is due to resonance stabilisation. The lone pair on chlorine can participate in delocalisation (resonance) to give two cannonical structures.
The carbon-chlorine bond in vinyl chloride has some double bond character and is therefore, stronger than a pure single bond.

Potassium permanganate
Potassium chlorate
Hypo
Potassium dichromate
