The cn– ion is widely used in the synthesis of organic compounds. what is the pattern of electron pairs in this ion? how many bonding pair(s) of electrons? how many lone pair(s) on the carbon atom? how many lone pair(s) on the nitrogen atom?

For the Lewis diagram of the cyanide ion, a figure is shown.

There are 3 pairs of bonding electrons. There is a one lone pair each for the carbon and the nitrogen atoms.

I hope I was able to answer your question. Thank you!
