Determine the bond angle for the following compound:BeCl2.
A
90°
B
180°
C
109.5°
D
120°
Verified step by step guidance1
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 based on the number of bonding pairs and lone pairs. With two bonding pairs and no lone pairs, BeCl2 adopts a linear geometry.
Understand that in a linear geometry, the bond angle between the two chlorine atoms is 180°.
Conclude that the bond angle for BeCl2 is 180°, as it corresponds to the linear arrangement of atoms.
