In AI2CI6, which statement is incorrect? a)Four AI-CI bond are same of...
Statement a) Four AI-CI bond are same of length and two of different length
This statement is incorrect. In AI2CI6, there are six AI-CI bonds, and all of them are of the same length. This is because all the chlorine atoms (CI) are bonded to the central atom, which is the AI (Aluminum). The AI atom is surrounded by six CI atoms, forming an octahedral geometry.
Explanation:
To understand why all the AI-CI bonds in AI2CI6 are of the same length, we need to consider the electronic and molecular geometry of the compound.
- Electronic configuration:
Aluminum (AI) has an atomic number of 13, which means it has 13 electrons. It has a configuration of 1s2 2s2 2p6 3s2 3p1. Chlorine (CI) has an atomic number of 17, with a configuration of 1s2 2s2 2p6 3s2 3p5.
- Octahedral geometry:
In AI2CI6, the AI atom is surrounded by six CI atoms, forming an octahedral geometry. This means that the CI atoms are arranged around the AI atom in a symmetrical manner, with bond angles of 90 degrees.
- Bond length:
In an octahedral geometry, all the AI-CI bonds are equivalent because they are formed by the overlap of the AI 3p orbital with the CI 3p orbital. This results in the formation of six identical AI-CI sigma bonds. Therefore, all AI-CI bonds in AI2CI6 have the same length.
In conclusion, the incorrect statement in AI2CI6 is that there are four AI-CI bonds of the same length and two of different length. In reality, all six AI-CI bonds are of the same length due to the octahedral geometry of the compound.
