Question

Name the following radicals: $\left(\mathrm{i}\right){\mathrm{Cr}}_2{{\mathrm{O}}_7}^{2-}\left(\mathrm{ii}\right){{\mathrm{HCO}}_3}^{-1}$

Answer 1

The names of the given ions :

${\mathrm{Cr}}_2{{\mathrm{O}}_7}^{2-}:$

• The given ion is named as Dichromate.
• It is known as a divalent inorganic anion obtained by the removal of both protons from Dichromic acid.
• It can be also named as a Chromium oxoanion or a divalent inorganic anion which is the conjugate base of a hydrogen dichromate.
• The structure for the ion can be given as :

${{\mathrm{HCO}}_3}^{-1}$:

• The given ion is named as Bicarbonate.
• It is known as an intermediate formed in the deprotonation of Carbonic acid.
• It is also termed as a polyatomic anion which serves a crucial biochemical role in the physiological pH buffering system.
• The structure for the ion can be given as :

Hence, the name of the given ions are ${\mathrm{Cr}}_2{{\mathrm{O}}_7}^{2-}:$Dichromate and ${{\mathrm{HCO}}_3}^{-1}$:Bicarbonate.
