# What type of bond would be formed if dyz orbitals overlap along the z axis? [duplicate]

I know that when two $\ce{p_z}$ orbitals overlap in a particular direction - along the z axis - they form a sigma bond. Now, if two $\ce{d_{yz}}$ orbitals overlap in same direction, which type of covalent bond would be formed?

Before I answer the question, you should understand that - since everything is symmetric - the answer would be the same if we took two $\ce{d_{yz}}$ orbitals along the x-axis, two $\ce{d_{xy}}$ orbitals along the y-axis, etc.

Have a look at this snippet I picked from Wikipedia Commons (by Jeremy77, public domain):

Here you can see the overlap of two $\ce{d_{xy}}$ orbitals along the y-axis constructively (in the same phase). There are four lobes overlapping, which would lead to a total of two nodal planes. Such a bond is a speciality of $\ce{d}$ orbitals and it is called the delta ($\delta$) bond.

Now, can you understand what the answer to your question would be?

• Just tell me in one word what is the answer of this question. Jul 1 '18 at 3:15
• @RohanSachdeva I said in my answer it's the delta bond Jul 1 '18 at 3:23
• Is delta bond resulting when $d_{x^2-y^2}$ and $p_y$ overlap along $y-axis$? Aug 20 '18 at 3:39
