Chapter 9: Chemical Bonding I:The Lewis Model
Given information
Here we have been priovided with two Nitrogen Compounds , and we have asked to find out which of them has the stronger nitrogen–nitrogen bond and the shorter nitrogen–nitrogen bond
Step-by-step explanation
Bond Strength is proportional to the number of bonds between the atoms. It is expected that the bond is stronger if more bonds are present. In contrast bond strength is inversely proportional to the length of the bond. A strong bond corresponds to a shorter bond length.
hence we are asked to show the stronger nitrogen-nitrogen bond in ,compounds.
Lewis dot structure is drawn below
Let's draw the Lewis Structure to compare the bond.
N2H4
N2H4 lewis structure is made up of two nitrogen and four hydrogens having two lone pairs on the nitrogen atoms(one lone pair on each nitrogen) and containing a total of 10 shared electrons.
There are three types of bonds present in the N2H4 lewis structure, one , and two .
