Guida verificata passo dopo passo1
Identify the central atom in the compound BeCl2, which is beryllium (Be).
Determine the number of electron pairs around the central atom. Beryllium typically forms two bonds with chlorine atoms, and there are no lone pairs on beryllium in BeCl2.
Recognize the molecular geometry of BeCl2. With two bonding pairs and no lone pairs, the geometry is linear.
Understand that in a linear geometry, the bond angle is 180° because the atoms are arranged in a straight line.
Conclude that the bond angle for BeCl2 is 180°, which corresponds to the linear arrangement of the atoms.
