help needed to draw lewis structures of hydrogen cyanaide(HCN) and cyanogen(CN)2. I need to show where the electrons are being shared clearly.



H:C:::N:

shared electrons, all upper dots except the ones to the right of N.

:N:::C:C:::N:
shared, all inner upper dots.

thank you for your help and such a speedy response
