Can you resend the image? It's not loading for me

JJeepaglu Can you resend the image? It's not loading for me

The image is actually blank because I couldn’t find any picture related to my doubt[any picture wouldn't be really helpful ig]. The posting required an attachment, so I had to upload a blank one

________OP•7/20/25, 12:42 PM

(I'm new to this concept so I might be missing something basic)

@Enamine your domain

Shhh•7/20/25, 12:59 PM

Because u need to know the shape of the diagram u will get it easily

Shhh•7/20/25, 12:59 PM

Send it

Does that clear it up? @Jeepaglu @__

is it like mandatory for two orbitals to have e density along the same axis to intermix?

________OP•7/20/25, 2:51 PM

moreover, can the z and x axis or the z and y axis form the equatorial plane?

________OP•7/20/25, 2:51 PM

Idk man I feel like I'll need to spend some time more with this

________OP•7/20/25, 2:51 PM

then these doubts will automatically clear up

What if the plane horizontal is xz or yz plane

GGBBEAST What if the plane horizontal is xz or yz plane

Varun_Arora•7/20/25, 2:56 PM

Internuclear axis ke hisab se change kar lo

_________is it like mandatory for two orbitals to have e density along the same axis to i...

Varun_Arora•7/20/25, 2:57 PM

Ahmm geometrically accessible hona chahiye like

________OP•7/20/25, 2:57 PM

see I kind of feel like

________OP•7/20/25, 2:57 PM

if we switch up these axes

________OP•7/20/25, 2:57 PM

we'll have to swicth the names of the orbitals themselves(this is just like a very vague guess which prob isnt true)

________OP•7/20/25, 2:57 PM

so for the sake of the simplicity

________OP•7/20/25, 2:58 PM

Ill just ask

________OP•7/20/25, 2:58 PM

why is the d orbital having that single dumb bell shape with a ring is involved in sp3d hybridisation

GBBEAST•7/20/25, 2:59 PM

@Enamine

GBBEAST•7/20/25, 3:00 PM

Like agar aisa hai toh dz2 kaha rakhenge

GBBEAST•7/20/25, 3:00 PM

I am just asking maybe this could be completely wrong

GBBEAST•7/20/25, 3:00 PM

Sorry the horizontal axis is z

GBBEAST•7/20/25, 3:00 PM

Not y

Jeepaglu•7/20/25, 3:01 PM

Oh wait mujhe samajh gya

_________why is the d orbital having that single dumb bell shape with a ring is involved ...

Varun_Arora•7/20/25, 3:01 PM

Why not? Most of its electron density is on the axis

Jeepaglu•7/20/25, 3:01 PM

Wait

Jeepaglu•7/20/25, 3:01 PM

Nvm

Jeepaglu•7/20/25, 3:01 PM

Won't pz and dz2 orbitals collide

JJeepaglu Won't pz and dz2 orbitals collide

GBBEAST•7/20/25, 3:02 PM

Yeah that's what I am asking

GBBEAST•7/20/25, 3:02 PM

Ohhh

Jeepaglu•7/20/25, 3:02 PM

And won't the negative plane around the dz2 orbital collide with the px py orbitlad

GBBEAST•7/20/25, 3:02 PM

Which mean we can't take dx2-y2

GBBEAST•7/20/25, 3:02 PM

Because it will intersect the plane

GBBEAST•7/20/25, 3:02 PM

So dz2 is the only choice

GBBEAST•7/20/25, 3:02 PM

I get it

Jeepaglu•7/20/25, 3:02 PM

What about non axial

Jeepaglu•7/20/25, 3:03 PM

Like dxy

JJeepaglu What about non axial

GBBEAST•7/20/25, 3:03 PM

They would also intersect in case the horizontal plane is xz

GBBEAST•7/20/25, 3:03 PM

That is not a hybrid structure

Jeepaglu•7/20/25, 3:03 PM

Oht hat makes sense

Jeepaglu•7/20/25, 3:03 PM

But what about pz and dz2

GGBBEAST Which mean we can't take dx2-y2

________OP•7/20/25, 3:03 PM

if we switch up the places of px and pz

JJeepaglu But what about pz and dz2

GBBEAST•7/20/25, 3:04 PM

Like how are you arranging them what is the horizontal plane ?

_________if we switch up the places of px and pz

GBBEAST•7/20/25, 3:04 PM

It would not make any diff

GGBBEAST It would not make any diff

________OP•7/20/25, 3:05 PM

why?

Why is only the dz^2 orbital involved in sp3d hybridization and not the other d orbitals
