Which of the following is true regarding a charged coordination entity...
The charge of a coordination entity is written without the presence of the counter ion and is indicated outside the square brackets on the right side as a superscript with the number before the sign of charge.
Which of the following is true regarding a charged coordination entity...
Explanation:
In a charged coordination entity, the charge on the complex ion is written after the number.
When naming coordination compounds, the name of the coordination entity is written inside square brackets, followed by the charge of the complex ion. The charge is written as a superscript outside the square bracket on the right side.
For example, if we have a complex ion with a charge of +2, the name of the coordination entity will be written inside square brackets, followed by the superscript +2 outside the square bracket on the right side.
Example:
[Co(NH3)6]2+
In this example, [Co(NH3)6] is the coordination entity and 2+ is the charge on the complex ion.
Options:
a) The charge is indicated as a subscript outside the square bracket on the right - This is incorrect. The charge is indicated as a superscript, not a subscript.
b) The charge of the complex ion is written in parenthesis while naming the entity - This is incorrect. The charge is written as a superscript outside the square bracket, not in parenthesis.
c) The sign of the charge is written after the number - This is correct. The charge on the complex ion is written after the number, indicating the sign of the charge.
d) The charge on the complex ion is depicted along with the counter ion - This is incorrect. The charge on the complex ion is not depicted along with the counter ion. The charge on the complex ion is written separately as a superscript outside the square bracket.
Therefore, the correct option is c) The sign of the charge is written after the number.
