How is the valency of carbon satisfied in methane?
Answer and explanation
Correct answer: Carbon forms four single bonds with four hydrogen atoms
Carbon has four valence electrons and therefore commonly shows valency four. In methane, its formula is CH₄: one carbon atom shares one electron with each of four hydrogen atoms. These shared pairs form four C–H single covalent bonds, giving carbon a stable octet and each hydrogen a stable duplet. The alternatives describe other or incomplete bonding, so option A is correct.
