Covalent Bond Formation in Different Molecules:
A student observes the electron dot structures of four molecules formed by sharing electrons.
| Molecule | Formula |
| P | \(Cl_{2}\) |
| Q | \(O_{2}\) |
| R | \(N_{2}\) |
| S | \(CH_{4}\) |
1. "As we move from P to R, the number of shared electron pairs increases by one".
Which option supports the statement? - .
2. Which molecule helps its central atom attain an octet by forming four covalent bonds? - .
