A)  Only \[{{N}_{2}}{{O}_{5}}\]

B) \[{{N}_{2}}{{O}_{3}}\]and\[{{N}_{2}}{{O}_{4}}\]

C)  \[{{N}_{2}}{{O}_{3}}\]and\[{{N}_{2}}{{O}_{5}}\]

D)  \[{{N}_{2}}{{O}_{4}}\]and\[{{N}_{2}}{{O}_{5}}\]

Correct Answer: B

Solution :

                 Among the oxides of nitrogen\[{{N}_{2}}{{O}_{3}},{{N}_{2}}{{O}_{4}}\]and \[{{N}_{2}}{{O}_{5}};\]the molecule(s) having nitrogen-nitrogen bond are                 \[{{N}_{2}}{{O}_{3}}\]and \[{{N}_{2}}{{O}_{4}}.\]whereas,\[{{N}_{2}}{{O}_{5}}\] has nitrogen-oxygen bonds only.
