What is a multiple bond? Give the difference between a single bond,a double bond,and a triple bond.

(N/A) multiple bond is a covalent bond formed by the sharing of more than one pair of electrons between two atoms. When two atoms share two or more electron pairs,it is called a multiple bond (e.g.,double or triple bonds).
| Feature | Single Bond | Double Bond | Triple Bond |
| :--- | :--- | :--- | :--- |
| Electron pairs shared | $1$ pair ($2$ electrons) | $2$ pairs ($4$ electrons) | $3$ pairs ($6$ electrons) |
| Representation | $-$ | $=$ | $\equiv$ |
| Example | $Cl_2$ $(Cl-Cl)$ | $O_2$ $(O=O)$ | $N_2$ $(N\equiv N)$ |
