Question

find hybridisaton in H^3O​

Answer 1

$\huge\underbrace\mathfrak\red{answer}$

Hybridization of H3O+ is sp3 and it's geometry is tetrahedral. The hybridisation in the central atom of is and geometry is trigonal pyramidal

Extra information ⬇️

Let hybridization , let suppose H3O+ as mentioned in the question.

We will consider the central atom of the molecule for Hybridization.

In this case we have Oxygen atom as central atom, so only Oxygen will undergo Hybridization.

Hydrogen is not going to Hybridize.

Now, Lets discuss the type of hybridization in this case.

We have four groups on our central atom( O ) :

3 Hydrogen atoms

1 Lone pair of electron

Simple way to understand the number of hybrid orbitals that we need , is to find out , how much groups are attached to the central atom
