Question:
Show the formation of the following molecules:
(A) Carbon dioxide (CO₂)
(B) Hydrogen sulfide (H₂S)
(C) Ammonia (NH₃) [Pg. No. 171]
Answer:
Verified
(A) Carbon has 4 valence electrons and each oxygen has 6 valence electrons. Carbon shares two pairs of electrons with each oxygen atom, forming two double covalent bonds.
Electron Dot Structure:
(B) Sulfur has 6 valence electrons and each hydrogen has 1 valence electron. Sulfur shares one electron each with two hydrogen atoms, forming two single covalent bonds.
Electron Dot Structure:
(C) Nitrogen has 5 valence electrons and each hydrogen has 1 valence electron. Nitrogen shares one electron with each of three hydrogen atoms, forming three single covalent bonds.
