Interpretation:
To analyse whether the given statement -The name of a binary ionic compound consists of the name of the positive ion followed by the name of the negative ion, is true or not.
Concept Introduction:
A covalent bond is formed by sharing of same number of electrons between two atoms to complete their octet. Atoms taking part in covalent bond formation may share one, two or three electron pairs thus forming single, double and triple bond respectively.
A binary covalent compound contains two kinds of atoms.
A covalent compound can be made of a atoms of the same element like Hydrogen, Oxygen etc, or it may be formed by atoms of different elements like
According to the rules for naming, binary covalent compound is named in this order-first the less electronegative element and then the more electronegative element.
Answer to Problem 31P
The name of a binary ionic compound consists of the name of the positive ion followed by the name of the negative ion. Thus, the statement is true.
Explanation of Solution
According to the rules for naming, binary covalent compound is named in this order-first the less electronegative element and then the more electronegative element.
For Example-
Electronic configuration of Beryllium, 2,2.
Valence shell has 2 electrons.
But to follow octet rule valance shall requires 8 electrons, for that it donates its 1 electron to two fluorine each.
On ejecting of 2 electrons now valence shell for Beryllium counts only 2 electrons, which completes its duplet. Hence it follows the octet rule.
Since, beryllium forms a cation it is written first, and Fluorine forming an anion is written later.
Therefore, the name of a binary ionic compound consists of the name of the positive ion followed by the name of the negative ion.
(b)
Interpretation:
To analyse whether the given statement -In naming binary ionic compounds, it is necessary to state the number of each ion present in the compound, is true or not.
Concept Introduction:
Binary compounds are those compounds which have atoms of two different elements. Since, the compounds are different, there is some difference in the electronegativity in the atoms and generally formation of a polar covalent bond takes place.
Binary compounds may or may not have the same ratio in all the existing atoms. For example: carbon monoxide, CO contains 1 carbon and 1 oxygen atom but carbon dioxide
Answer to Problem 31P
In naming binary ionic compounds, it is necessary to state the number of each ion present in the compound. Thus, the statement is true.
Explanation of Solution
Binary compounds may or may not have the same ratio in all the existing compound.
For example: carbon monoxide, CO contains 1 carbon and 1 oxygen atom but carbon dioxide
For example: In Iron (II) oxide, FeO, the ratio of Iron and Oxygen is 1:1 but in Iron (III) oxide,
Therefore. in naming binary ionic compounds, it is necessary to state the number of each ion present in the compound.
