HCN is called Hydrogen cyanide. First we need to count the total number of valence electron. We just add the valence electron of each atom involved.

C = 4

O = 5

H = 1

HCN is called Hydrogen cyanide. First we need to count the total number of valence electron. We just add the valence electron of each atom involved.

C = 4

O = 5

H = 1

------------

        10 electrons

Next, we have to assign the central atom; In this case it is C.

Now we have to connect the atoms and form a bond. We have now C---N (triple bond) , and a C-H bond

`H -C-=N`

Finally, we have to distribute The remaining electrons on N provided that it follows the octet rule.

` H -C-=N: `

HCN contains a triple bond and therefore it is a linear molecule. Linear molecules have 180 degrees bond angles.
