In the following electron dot structure,the correct calculation of the formal charge on the nitrogen atoms from left to right is $\overset{\centerdot \centerdot}{\mathop{N}}\text{=}\mathop{N}\text{=}\overset{\centerdot \centerdot}{\mathop{N}}$

Identify the option$(s)$ which contain correct statements.

Bonds present in $CuSO_4 \cdot 5H_2O$ are

Identify the correct orders against the property mentioned:
$(A)$ $H_2O > NH_3 > CHCl_3$ - dipole moment
$(B)$ $XeF_4 > XeO_3 > XeF_2$ - number of lone pairs on central atom
$(C)$ $O-H > C-H > N-O$ - bond length
$(D)$ $N_2 > O_2 > H_2$ - bond enthalpy
Choose the correct answer from the options given below:

Draw Lewis structures of the following molecules and ions: $H_2S$,$SiCl_4$,$BeF_2$,$CO_3^{2-}$,$HCOOH$.

$O-O$ bond length in $H_2O_2$ is $\underline{X}$ than the $O-O$ bond length in $F_2O_2$. The $O-H$ bond length in $H_2O_2$ is $Y$ than that of the $O-F$ bond in $F_2O_2$. Choose the correct option for $\underline{X}$ and $\underline{Y}$ from the given below.
