Is C2H2 AB2 type?

To determine if C2H2 is AB2 type, we need to analyze its molecular structure.

1. First, let's draw the Lewis structure of C2H2.

C2H2 consists of two carbon atoms (C) and two hydrogen atoms (H). The carbon atoms are connected by a triple bond, and each carbon atom is bonded to one hydrogen atom.

2. Next, let's count the total number of electron pairs around each carbon atom.

Each carbon atom has three electron pairs: one from the triple bond with the other carbon atom and two from the single bonds with the hydrogen atoms.

3. Now, let's determine the molecular geometry of C2H2.

Since there are only two electron pairs around each carbon atom, the molecular geometry is linear.

4. Finally, let's analyze the AB2 type.

In the AB2 type, A represents the central atom, and B represents the surrounding atoms. Since C2H2 has a linear molecular geometry, it does not fit the AB2 type.

Therefore, C2H2 is not AB2 type.
