Why sp3 hybridisation in NH3 but bonding with pure p orbitals in case of other hydrides of group 15 [duplicate]
According to my book, the following line was given relating to the bond angle in Group 15 elements
The bond angle in PH3, AsH3 and SbH3 is close to 92° which suggests that the orbitals used for ...

What is Bent's rule?
I'm all bent out of shape trying to figure out what Bent's rule means. I have several formulations of it, and the most common formulation is also the hardest to understand.
Atomic s character ...

Why does bond angle decrease in the order H2O, H2S, H2Se?
I know that bond angle decreases in the order $\ce{H2O}$, $\ce{H2S}$ and $\ce{H2Se}$. I wish to know the reason for this. I think this is because of the lone pair repulsion but how?

Why does basicity of group 15 hydrides decrease down the group?
In my textbook it is written that the order of basic strength of pnictogen hydrides is
$$\ce{NH3 > PH3 > AsH3 > SbH3 > BiH3}$$
I tried but could not find any explanation as to why this ...

What is Drago's rule? Does it really exist?
My textbooks states the Drago's rule in inorganic chemistry as follows:
The more electronegative atom prefers the orbital having more $\mathrm{p}$ character, and lone-pairs or less electronegative ...

Why is the inversion barrier larger in PH3 than it is in NH3?
The inversion barrier in $\ce{NH3}$ is approximately $5~\mathrm{kcal~mol^{-1}}$ and that of $\ce{PH3}$ is $35~\mathrm{kcal~mol^{-1}}$. This has well-known stereochemical consequences in that amines ...

Why the bond angle of PH3 is lesser that that of PF3?
We can explain why the bond angle of $\ce{NF3}$ (102°29') is lesser than $\ce{NH3}$ (107°48') by the VSEPR theory, since lone pair lone pair repulsion is greater than lone pair bond pair repulsion. ...

Why does SO2 have a larger bond angle than H2O, H2S, and NH3
So we have to find which of the follwing compounds has the smallest bond angle:
$\ce{H2O}$, $\ce{H2S}$, $\ce{NH3}$, $\ce{SO2}$.
So L $\propto \frac{1}{BA}$
where $L$ is the number of lone pairs and $...

Hybridization in PH3
Does $\ce{PH3}$ exhibit $\ce{sp^3}$ hybridization?
Arguments against hybridization:
$\ce{PH3}$ is less basic than $\ce{NH3}$.
This jibes with the supposition that $\ce{PH3}$ keeps its lone pair in ...

How do electronegativity and lone pairs affect bond angles?
How do bond angles vary in molecules with a lone pair and central atom of different electronegativity, but in the same period so that electronegativity matters more than orbital size? Let's assume ...

What is the hybridization state of E (= Sn, C) in ECl₂?
What is the hybridization state of tin in tin(II) chloride, $\ce{SnCl2}$, and is the explanation similar for dichlorocarbene, $\ce{CCl2}$?
For $\ce{SnCl2}$, I read in my book that it is sp² but I am ...

Why does NCl3 use sp³ hybrid orbitals?
I have a question regarding the hybridization of $\ce{NCl3}$.
From what I've understood, hybridization occurs when electrons belonging to different orbitals mix.
For example an electron belonging to ...

Does Bent's Rule only apply to molecules where there is hybridisation?
I would just like to ask if the pre-requisite for using Bent's Rule is that the bonding in the molecule involves hybridised orbitals.
I was thinking of why the bond angle in hydrogen sulfide (~ 92 ...

Also, don't hybrid orbitals appear in all molecules?
The answer by "ron" says "the molecule can be viewed as being unhybridized":
