(A) Write a Lewis structure for nitrosyl chloride based on the skeletal structure N—O—Cl and show that this structure is not as plausible as the one obtained in Example 10-8.

(B) Write two Lewis structures for cyanamide, NH₂CN, an important chemical of the fertilizer and plastics industries. Use the formal charge concept to choose the more plausible structure.

Example 10-8

Write the most plausible Lewis structure of nitrosyl chloride, NOCl, one of the oxidizing agents present in aqua regia, a mixture of concentrated nitric and hydrochloric acids capable of dissolving gold.
