Hello everyone.
00:02
So for the given question, we need to find when these pair of orbitals are allowed to overlap, which pair of orbital will result in the formation of a pi bond? so these are the four options that are given to us.
00:12
So first we need to know about the type of bond, that is the sigma bond and the pi bond.
00:17
So what is the sigma bond? so a sigma bond is a type of covalent bond that is found by head -on overlap of atomic orbitals along the inter -nuclear axis.
00:27
And a pi bond is a type of covalent bond that is found by side -based overlap.
00:30
Of atomic orbitals along a direction that is perpendicular to the inter -nuclear axis.
00:35
So if we look at the atomic orbitals and let's say that this is the inter -nuclear axis.
00:40
So in this case we can say that here we have been given the dumble -shaped p -orbitals and there is the head -on overlap along the inter -nuclear axis.
00:53
So the bond formed will be a sigma bond.
00:58
Now in the second case, if we again take a inter -nuclear axis something like this, now we can say that the dumbled shape b orbitals are forming a sideways overlapping of the atomic orbitals along the direction that is perpendicular to the internuclear axis.
01:15
So in this case a pi bond will be formed by the sideways overlap of the orbital.
01:21
So we can write that a pi bond is formed...
