All right. Hi, everyone. So for this question, let's determine which element from group four A forms the strongest P bot option A says carbon option B says silicone option C says Germanium and option D says lead. Now, recall it for a question like this, right? In order to assess which of these elements forms the strongest pi bond, we're wondering about the size of these atoms relative to each other, right? Because recall that in order for a pi bond to form, there has to be overlap between the P orbitals of a given element pu right? So when we consider the size of a given element, we're considering how well its P orbitals can overlap with each other in order to create this pi bond. And recall also that's smaller elements are better capable of this P orbital overlap because recall that smaller sized atoms have their P orbitals less diffuse or less spread out, which means that they can better overlap with each other and create shorter bonds and therefore stronger bonds, right? So as the size of the atom gets smaller, so does the bond distance therefore making it stronger. Now, because we're talking about elements in the same group. Recall that the size of an atom increases as you go down a group in the periodic table. Therefore, carbon being the first element in group four A is actually the smallest and there you have it right. And it just so happens that Corbin is found oops in period two or in other words, the second row of the periodic table and recall that second row elements are characteristically small, which is what allows them to form multiple bonds due to this easy pie overlap. And there you have it, our answer is going to be option a in the multiple choice which is carbon. So with that being said, thank you so very much for watching. And I hope you found this helpful.
