The correct order of increasing bond length of $C - H, C - O, C - C$ and $C=C$ is

Match the species in List-$I$ with their geometry in List-$II$:

List-$I$	List-$II$
$A. PCl_5$	$I. \text{Tetrahedral}$
$B. BrF_5$	$II. \text{Square Planar}$
$C. BF_4^-$	$III. \text{Trigonal bipyramidal}$
$D. [Ni(CN)_4]^{2-}$	$IV. \text{Square pyramidal}$

Choose the correct answer from the options given below:

Which of the following are isostructural pairs?
$A.$ $SO_{4}^{2-}$ and $CrO_{4}^{2-}$
$B.$ $SiCl_{4}$ and $TiCl_{4}$
$C.$ $NH_{3}$ and $NO_{3}^{-}$
$D.$ $BCl_{3}$ and $BrCl_{3}$

Given below are two statements:
Statement $I$: $F_2O < H_2O < Cl_2O$ is the correct trend in terms of bond angle.
Statement $II$: $SiF_4, SnF_4$ and $PbF_4$ are ionic in nature.

$Me_3B$,$BH_3$,and $BF_3$ are three Lewis acids. Which one of the following is the correct sequence of these acids in order of their increasing acid strength?

$A$ tin chloride $Q$ undergoes the following reactions (not balanced):
$Q + Cl^{-} \rightarrow X$
$Q + Me_3N \rightarrow Y$
$Q + CuCl_2 \rightarrow Z + CuCl$
$X$ is a monoanion having pyramidal geometry. Both $Y$ and $Z$ are neutral compounds. Choose the correct option$(s)$.
$(1)$ The central atom in $X$ is $sp^3$ hybridized
$(2)$ The oxidation state of the central atom in $Z$ is $+4$
$(3)$ The central atom in $Z$ has no lone pair of electrons
$(4)$ There is a coordinate bond in $Y$
