Question
Explain the bonding in methane molecule using electron dot structure.
✓
Answer
Formation of methane molecule – Non-polar covalent compound:
One atom of carbon shares four electron pairs, one with each of the four atoms of hydrogen.
| Atom | Electronic configuration | Nearest noble gas | To attain stable electronic the configuration of nearest noble gas |
| Carbon | ${ }_6^{12} C [2,4]$ | Neon $[2,8]$ | Carbon needs four electrons to complete the octet |
| Hydrogen | ${ }_1^1 H [1]$ | Helium [2] | Hydrogen needs one electron to complete the duplet |
 |
|
| Before combination $(4[ H ]$ and 1 $[ C ]$ atom) | After combination $( CH 4$ - Methane molecule) |
