Step 1
Possible shapes of molecules of general formula QX<sub>2</sub>
Answer
-
Linear (Straight): This shape occurs when there are no lone pairs on the central atom Q, leading to a straightforward arrangement of the bonding pairs of electrons.
-
Bent (Angular / V-shaped): This shape arises when there are lone pairs on the central atom Q, affecting the bond angles and giving the molecule a bent appearance.
