First let\'s draw out the Lewis structure such that each atom has either an octet (C and N), or 2
electrons (H)
The only way to do this is:
H-C=N:
There is a C-N triple bond and a lone pair on the N.
Now, the steric number is defined as the number of bonds to another atom + the number of lone
pairs on the atom.
For H: 1 bond = steric number of 1.
For C: 4 bonds (1 single + 1 triple) = steric number of 4 (carbon almost always has SN = 4)
For N: 3 bonds (1 triple) + 1 lone pair = steric number of 4 (nitrogen also often has SN = 4)
Solution
