  • What does pseudo halide ion mean?

  • @sankarshana-nanjangud
    The pseudohalogens are polyatomic analogues of halogens, whose chemistry, resembling that of the true halogens, allows them to substitute for halogens in several classes of chemical compounds.

    The general form is Ps–Ps or Ps–X (where Ps is a pseudohalogen group), such as cyanogen; pseudohalide anions, such as cyanide ion; inorganic acids, such as hydrogen cyanide.

    Pseudohalides are "fake halides." Their chemistry bears some resemblance to true halides
    (F−, Cl−, Br−, I−).

    Examples of pseudohalides include CN− and N3−. These are generally weak Lewis bases that bear a formal negative 1 charge.
