(1) Ozone is not poisonous in nature $\rightarrow$ Ozone that is present at the ground level near troposphere is called as bad ozone which acts as pollutant in the air. This air pollutant creates harm to the human health and plants. The smog that is formed in the cities constitutes ozone.
(2) Ozone is a linear molecule $\rightarrow$ Ozone is a bent molecule, with an $O-O-O$ bond angle of $117 ^{\circ}$
(3) Flourine forms six salts with Xenon. These are XeF$_2$, XeF$_3$,XeF$_4$, XeF$_5$, XeF$_6$, XeF$_7 \rightarrow$ Only three halides Flourine forms six salts with Xenon. These are XeF$_2$, XeF$_4$, and XeF$_6$ are known to us.
