Which type of hybrid orbitals on a carbon atom, s p, s p^2,...

Key Concepts

Hybridization

Hybridization is a concept in molecular chemistry where atomic orbitals mix to form new hybrid orbitals, which in turn determine the geometry of the molecule. For carbon, sp hybridization results in a linear geometry, sp2 in a trigonal planar geometry, and sp3 in a tetrahedral geometry. The spatial arrangement of these geometries affects how substituents are positioned around the atom.

Chirality

Chirality refers to the property of a molecule when it cannot be superimposed on its mirror image, resulting in a pair of enantiomers. This property typically arises in molecules where a central atom, usually a carbon atom, is bonded to four different substituents in a tetrahedral arrangement. The lack of symmetry in such arrangements, which is possible with sp3 hybridization, allows for the existence of non-superimposable mirror images.

Transcript

00:01 So in this question, we're asked to determine which type of hybrid orbitals on a carbon atom, sp, sp2, or sp3 can give rise to enansomers.

00:12 So we know that an enansomar is a carbon that has to be an achyro molecule.

00:17 So an acyro molecule is a carbon that is surrounded by four different types of molecules.

00:22 So we need to determine the hybridization of that carbon.

00:25 So a way we can approach this problem is give examples of what an sp, sp2, or sp3, carbon would look like.

00:33 So an sp carbon would look something like this.

00:35 It would be a carbon, and then it would have a triple bond to another carbon, and then carbon needs to have four bonds at all times.

00:44 So there would be two hydrogens here, and this is going to be sp, right? and so the carbon is going to be sp away from each other.

00:53 That's the hybridization of this molecule.

00:55 And then sp2 would look something like this.

00:59 It would be a carbon, double bonded to a carbon, and then, then bond to a hydrogen here and a hydrogen here.

01:06 And then same thing on the other side.

01:07 And the reason why is because carbon needs four bonds.

01:10 So it looks something like this.

01:12 And it would be sp2 hybridized.

01:20 And then finally, an sp3 hybridized carbon would look something like this.

01:24 It would be a carbon and then it would say like have another carbon and then it would have three other molecules.

01:33 So they don't necessarily have to be hydrogen.

01:35 I'm just, i'm just, you know, writing hydrogen to make it simple.

01:39 So this is what an sp3 hybridized molecule would look like.

01:42 So we need to determine which of the volume could give rise to enanshumors...
