Question

The oxygen atom in alcohal is

Sp hybridised

Sp2 hybridised

Sp3 hybridised

None of these

Answer 1

Answer:

$\bold\red{(3)\:s{p}^{3}\:hybridised}$

Explanation:

We know that an and alcohol consists of R-O-H bond .

Here, R is an alkyl group.

Now, oxygen has made two bonds , one with alkyl group and another with Hydrogen.

Also, There are two lone pairs on oxygen atom.

But, we know that, Hybridisation is decided by factors , that are

1. Number of bonds formed
2. Number of lone pairs present

So, according to this,

One sigma bond decides s-character .

Another pi bond decides p-character.

and,

The other two lone pairs decide two more p-character.

So, there are total 3 p-character.

So, summing up, we get Hybridisation as $\red{s{p}^{3}}$.

Answer 2

$\huge\underline\mathfrak\red{Answer}$

Sp3 hybridised
