exists in two isomeric forms ‘A’ and ‘B’. Isomer ‘A’ reacts with
to give white precipitate, but does not react with
. Isomer ‘B’ gives white precipitate with
but does not react with
. Answer the following questions.
(i) Identify ‘A’ and ‘B’ and write their structural formulas.
(ii) Name the type of isomerism involved.
(iii) Give the IUPAC name of ‘A’ and ‘B’.
:
(i). The first isomer A reacts with and not with
, that means it has a
ion outside the coordination sphere. Therefore, A is
B reacts with and does not react with
, that means it has
outside the coordination sphere. Therefore B is
(ii). Ionisation Isomerism
(iii). A is Pentaamminesulphatocobalt (III) chloride while B is Pentaamminechlorocobalt (III) sulphate.
