Among the following statements, correct statements are:

(i) $\mathrm{CO}$ and ${\mathrm{N}}_2$ have same bond order

(ii) ${\mathrm{O}}_2^{+}$ is more stable than ${\mathrm{O}}_2$

(iii) Bond order of $\mathrm{C}{\mathrm{O}}^{+}$ and ${\mathrm{N}}_2^{+}$ is same

(iv) MOT explain diamagnetic character of oxygen

(v) HOMO of ${\mathrm{F}}_2$ molecule is ${\mathrm{\sigma }}_2^{\mathrm{*}}{\mathrm{P}}_{\mathrm{z}}$

 

Give a reason for the following:

Ionic compounds have a high melting point.

Two elements $\mathrm{A}$ and $\mathrm{B}$ have electronegativities $1.2$ and $3.0$ respectively. The nature of bond between $\mathrm{A}$ and $\mathrm{B}$ would be
