D
109.5°
Verified step by step guidance1
Identify the central atom in the thiocyanate ion (SCN–). In this case, the central atom is carbon (C).
Determine the number of electron domains around the central atom. For SCN–, carbon is bonded to sulfur (S) and nitrogen (N), and there are no lone pairs on carbon.
Recognize the molecular geometry based on the electron domain geometry. With two bonding pairs and no lone pairs, the electron domain 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 the thiocyanate ion (SCN–) is 180°, which corresponds to the linear molecular geometry.
