300-Word Explanation<\/strong><\/h3>\n\n\n\n

The bond length between atoms is influenced by the type and order of the bond. A triple bond is shorter and stronger than a double bond, which in turn is shorter and stronger than a single bond. Among the three given molecules \u2014 N\u2082H\u2084<\/strong>, N\u2082<\/strong>, and N\u2082F\u2082<\/strong> \u2014 the bonding between the two nitrogen atoms varies in bond order, leading to differences in bond lengths and strengths.<\/p>\n\n\n\n

In N\u2082 (dinitrogen)<\/strong>, the two nitrogen atoms are connected by a triple bond<\/strong>. This triple bond consists of one sigma bond and two pi bonds. It results in a very short and strong bond due to the high electron density shared between the atoms. As a result, N\u2082<\/strong> has the shortest and strongest<\/strong> nitrogen-nitrogen bond.<\/p>\n\n\n\n

N\u2082F\u2082 (difluorodiazene)<\/strong> has a double bond<\/strong> between the two nitrogen atoms. It has one sigma and one pi bond, resulting in a bond length longer than that of N\u2082 but shorter than a single bond. The presence of electronegative fluorine atoms may affect electron distribution but does not change the bond order between the nitrogen atoms.<\/p>\n\n\n\n

N\u2082H\u2084 (hydrazine)<\/strong> contains a single bond<\/strong> between the two nitrogen atoms. This bond is the longest and weakest<\/strong> among the three molecules because only one pair of electrons is shared. The lone pairs on each nitrogen may also cause repulsion, slightly increasing the bond length further.<\/p>\n\n\n\n

Thus, the nitrogen-nitrogen bond lengths increase in the order N\u2082 < N\u2082F\u2082 < N\u2082H\u2084<\/strong>, and the bond strength decreases in the same order. Therefore, N\u2082<\/strong> has the strongest nitrogen-nitrogen bond<\/strong>, a direct consequence of its triple bond.<\/p>\n\n\n\n
