$(I)$ and $(III)$ only

Vedclass · Answer

(A) Statement $(I)$ is correct: According to Fajan's rule,a higher oxidation state of the central metal atom leads to greater covalent character. $Sn$ in $SnCl_4$ $(+4)$ has a higher oxidation state than in $SnCl_2$ $(+2)$,making $SnCl_4$ more covalent.Statement $(II)$ is incorrect: Linear diatomic molecules like $HF$,$HCl$,and $HBr$ are polar and possess a non-zero dipole moment.Statement $(III)$ is correct: $NO$ has one unpaired electron and $O_2$ has two unpaired electrons in its antibonding molecular orbitals,making both paramagnetic.Therefore,statements $(I)$ and $(III)$ are correct.

List-$I$ (Classification of molecules based on octet rule)	List-$II$ (Example)
$A$. Molecules obeying octet rule	$I$. $NO, NO_2$
$B$. Molecules with incomplete octet	$II$. $BCl_3, AlCl_3$
$C$. Molecules with odd electron	$III$. $H_2SO_4, PCl_5$
$D$. Molecules with expanded octet	$IV$. $CCl_4, CO_2$

Identify the correct statements from the following.
$(I)$ $SnCl_2$ is ionic,but $SnCl_4$ is covalent in nature.
$(II)$ All linear diatomic molecules have zero dipole moment.
$(III)$ Both $NO$ and $O_2$ are paramagnetic.
