Question

Among the following, the pseudo halide is ______.

विकल्प

• CN⁻

• ICl

• \[\ce{I^-_3}\]

• IF₅

Answer 1

Among the following, the pseudo halide is CN⁻.

Explanation:

Pseudo halides are ions that behave similarly to halide ions. Among the given options, CN⁻ (cyanide ion) is a pseudo halide ion because it mimics the chemical behaviour of halides. The others are either interhalogen compounds (ICl), polyhalide ions (\[\ce{I^-_3}\]), or interhalogen pentafluorides (IF₅), which are not classified as pseudo halides.
