$Q + Cl ^{-} \rightarrow X$

$Q + Me _3 N \rightarrow Y$

$Q + CuCl _2 \rightarrow Z + CuCl$

$X$ is a monoanion having pyramidal geometry. Both $Y$ and $Z$ are neutral compounds. Choose the correct option($s$).

$(1)$ The central atoms in $X$ is $sp ^3$ hybridized

$(2)$ The oxidation state of the central atom in $Z$ is $+2$

$(3)$ The central atom in $Z$ has one lone pair of electrons

$(4)$ There is a coordinate bond in $Y$

Reason : Covalency of oxygen is two.
