Vedclass · Answer

(A) In a hydroxyl ion,$OH^{\ominus}$,the oxygen atom has $6$ valence electrons. It shares $1$ electron with the hydrogen atom to form a covalent bond,and it gains $1$ electron due to the negative charge. This results in $8$ electrons around the oxygen atom,which corresponds to $4$ electron pairs. Out of these $4$ pairs,$1$ pair is involved in the $O-H$ covalent bond,and the remaining $3$ pairs are lone pairs on the oxygen atom.

How many lone pairs of electrons are present in a hydroxyl ion?
