Interpretation:
The HONC 1234 rule must be explained.
Concept introduction:
HONC 1234 is the basic rule for drawing the structures of organic molecules containing C, H, N and O atoms.

Answer to Problem 1E
HONC 1234 rule states that H, O, N and C generally form 1, 2, 3 and 4 bonds respectively.
Explanation of Solution
HONC 1234 rule considers the valency of C, H, N and O atom. As the valency of C, H, N and O are 4, 1, 3 and 2 respectively so it is expected that C, H, N and O will form 4, 1, 3 and 2 bonds respectively.
