Where $A$ is $PCl^+_4$ while $B$ is $PCl^-_ 6$
Which of the following statement is INCORRECT :
$(I)$ $B$ to $A$ involvement of number of $d-$orbital in hybridization increases
$(II)$ $A$ to $B$ precentage of $p-$character in $P-Cl$ bond increases
$(III) $ Number of covalent bond in $A$ and $B$ are same
$(IV)$ $B$ is product of Lewis acid-base interaction which is associated with super octet molecule only
$C_2H_4O(g) \longrightarrow CH_4(g) + CO(g)$ If the initial pressure of $C_2H_4O(g)$ is $80\, mm$ and total pressure at the end of $20\, minutes$ is $120\, mm$ ............ $\min$
$M + L \rightleftharpoons ML$
$ML + L \rightleftharpoons M{L_2}$
are $4$ and $3$. Hence, overall stability constant for
$M + 2L \rightleftharpoons M{L_2}$ is
