Vedclass · Answer

(B) The chemical formula for chlorous acid is $HClO_2$.In the structure of $HClO_2$,the chlorine atom is bonded to one hydroxyl group $(-OH)$ and one oxygen atom via a double bond.The valence shell configuration of chlorine is $3s^2 3p^5$,meaning it has $7$ valence electrons.In $HClO_2$,chlorine forms $3$ bonds ($1$ with $O$ of $-OH$ group and $2$ with the other $O$ atom).Out of $7$ valence electrons,$3$ are involved in bonding,leaving $4$ electrons as lone pairs.Since $2$ electrons make $1$ lone pair,$4$ electrons correspond to $2$ lone pairs on the chlorine atom.

How many lone pairs of electrons are present on the chlorine atom in chlorous acid $(HClO_2)$?
