I was asked to draw a dot-and-cross diagram for chlorine dioxide, and I was wondering why Cl in ClO2 will form one double bond with one O atom and another dative bond with another O atom. (This was the answer my school gave.)
Why can't Cl form one double bond with one O atom and another double bond with another O atom? I learnt that when it comes to drawing dot-and-cross diagrams, we should always consider drawing single bond first, followed by double, triple and then finally, dative. Also, considering how Cl can expand its octet since its in Period 3...
Can anyone enlighten me as to why we can't draw 2 double bonds like O=Cl=O?
Thank you so so much!
