Monodentate Memes

This meme is a chemist's version of that infamous couch scene! In coordination chemistry, copper(II) ions typically form complexes with six water molecules - creating a hexaaquacopper(II) complex. Each H₂O is a monodentate ligand (meaning it forms just ONE bond to the central metal ion). The joke? Five H₂O molecules surround our Cu²⁺ ion while the "sixth H₂O is holding the camera" - a hilarious nod to the octahedral geometry of this complex! Chemistry students everywhere are simultaneously groaning and sending this to their study groups right now!
