Vedclass · Answer

(A) In the $HNO_3$ molecule,the $N-OH$ bond (labeled $a$) is a single bond with a bond order of $1$,which corresponds to a bond length of approximately $1.40 \,\mathring{A}$.
The $N-O$ bonds (labeled $b$) in the nitrate group exhibit resonance,resulting in a partial double bond character with a bond order of $1.5$,which corresponds to a shorter bond length of approximately $1.21 \,\mathring{A}$.

In the given $HNO_3$ molecule,identify the bond lengths $a$ and $b$ (where $a$ and $b$ are bond lengths).
