Answer: Option (1) is the correct answer.

Explanation:

A periodic table is a chart in which all the elements are placed in rows and columns according to their increasing atomic number from left to right side.

In a periodic table there are 18 columns and 7 rows.

All these elements are organized in such a way that elements which are present in same group show similar chemical properties.

Thus, we can conclude that the statement it provides a view of the elements organized by their properties best explains the value of the Periodic Table.

Select the true statements regarding these resonance structures of formate.? Each carbon-oyxgen bond is somewhere between a sing

son4ous [18]

Answer : Option 1) The true statement is each carbon-oxygen bond is somewhere between a single and double bond and the actual structure of format is an average of the two resonance forms.

Explanation : The actual structure of formate is found to be a resonance hybrid of the two resonating forms. The actual structure for formate do not switches back and forth between two resonance forms.

The O atom in the formate molecule with one bond and three lone pairs, in the resonance form left with reference to the attached image, gets changed into O atom with two bonds and two lone pairs.

Again, the O atom with two bonds and two lone pairs on the resonance form left, changed into O atom with one bond and three lone pairs. It concludes that each carbon-oxygen bond is neither a single bond nor a double bond; each carbon-oxygen bond is somewhere between a single and double bond.

Also, it is seen that each oxygen atom does not have neither a double bond nor a single bond 50% of the time.
