In a methane (CH₄} molecule, the number of electrons participating in bonding are:
1 4
2 2
3 1
4 8

Correct option is D

Correct Answer: (d)
Explanation
Methane ( CH₄} consists of:
· One carbon atom with 4 valence electrons.
· Four hydrogen atoms, each contributing 1 electron.
Carbon forms four single covalent bonds with four hydrogen atoms.
Each covalent bond contains 2 shared electrons.
Therefore,
Total bonding electrons = 4 × 2 = 8 electrons
Hence, the correct answer is Option d: 8.
Additional Information
• Electronic configuration:
· Carbon = 2, 4
· Hydrogen = 1
• Carbon completes its octet by sharing four electrons.
• Hydrogen completes its duplet by sharing one electron.
• Methane has:
· 4 C–H single covalent bonds
· Tetrahedral geometry
· Bond angle = 109.5°
