Question

Give IUPAC name of the ionisation isomer of [Cr (NH3)5Br]SO4. Draw the 2 structures of optical isomers of [CoBr2(Ox)2]3–

Answer 1

Answer:

PentaammineBromidochromium(III) Sulphate

Answer 2

Answer:

Pentammine bromo cobalt (III) sulphate is the IUPAC designation for the compound [Cr (NH3)5Br]SO4. [Cr(NH3)5So4]Br is its ionisation isomer.

The structure of optical isomers of [CoBr2(Ox)2]3- are also attached.

Explanation:

• Ionisation isomerism is the term used to describe the property of compounds that, despite having the same composition, produce distinct ions in a solution.
• The core ion and all of the other ligands are the same.
• When two isomers exhibit identical molecular weight, chemical, and physical properties, this is known as optical isomerism.
• Their impact on the rotation of polarised light, however, varies.
• Stereoisomers that rotate the plane of polarised light demonstrate optical isomerism.
• The enantiomer is said to exist in (+) form if the plane of polarised light passing through the enantiomer solution rotates in a clockwise direction, and in (-) form if the plane of polarised light rotates in an anti-clockwise direction (-).
• Optical Isomerism does not have any kind of symmetry whether it is Plane of symmetry or centre of symmetry.
• Optical Isomerism have non super imposable mirror images.
• It is also called enantiomers.

So we can conclude that the chemical compound [Cr (NH3)5Br]SO4 has the IUPAC name pentammine bromo cobalt (III) sulphate. [Cr(NH3)5So4] Its ionisation isomer is Br. Moreover The optical isomers of [CoBr2(Ox)2]3- structure is also attached.
