Question

6. a) Why is isocyanic acid prepared ""in situ"" in the Dulcin experiment? [2 pts] b) Draw a plausible Lewis structure for isocyanic acid showing all lone pairs. The connectivity for isocyanic acid is shown below[4 pts] H-N-C-0

Answer 1

As it gets hydrolyzed easily.

Step-by-step explanation:

The isocyanic acid may get polymerizes easily into cyanuric acid and a polymer cyamelide

Also, even at 0 °C temperature it may react with mositure and gets hydrolyzed into ammonia an carbon dioxide. Thus we generally prepare it in situ. Even after synthesis it is stroed at dry ice or liquid nitrogen at very low temperature.

The lewis structure is shown in the figure.
