The number of bridged oxygen atoms present in compound B formed...

The number of bridged oxygen atoms present in compound $B$ formed from the following reactions is

$Pb{\left({NO}_{3}\right)}_{2}\overset{673K}{⟶}A + PbO + {O}_{2}$

$A\overset{Dimerise}{⟶}B$

The number of bridged oxygen atoms present in compound B formed from the following reactions is Pb ( NO _ 3 ) _ 2 673K

Options

A $0$
B $1$
C $2$
D $3$

Correct answer

A. $0$

Step-by-step solution

Thermal decomposition of lead nitrate gives nitrogen dioxide.

$2Pb{\left({NO}_{3}\right)}_{2}\mathop{\overset{\Delta}{⟶}}_{673K}2PbO + 4{NO}_{2} + {O}_{2}$

$2{NO}_{2}\overset{Dimerisation}{⟶}{N}_{2}{O}_{4}$

The number of bridged oxygen atoms present in compound B formed from the following reactions is Pb ( NO _ 3 ) _ 2 673K
