C
90°
D
120°
Verified step by step guidance1
Identify the central atom in BeCl_2, which is beryllium (Be), and count the number of atoms bonded to it as well as any lone pairs on the central atom.
Draw the Lewis structure for BeCl_2: beryllium forms two single bonds with two chlorine atoms and has no lone pairs on the central atom.
Determine the electron domain geometry around the central atom using the VSEPR (Valence Shell Electron Pair Repulsion) theory, which considers both bonding pairs and lone pairs of electrons.
Since there are two bonding pairs and no lone pairs on beryllium, the electron domain geometry is linear.
Recall that a linear geometry corresponds to an ideal bond angle of 180°, which is the angle between the two Be-Cl bonds.
