The bond angle in tetrahedral molecules such as tetrachloromethane is

The bond angle in tetrahedral molecules like tetrachloromethane is 109.5°. This is because the molecule has a tetrahedral geometry, which means it has four atoms bonded to a central atom, with the angle between any two adjacent bonds being 109.5°. This angle is also known as the tetrahedral angle and is determined by the repulsion between the bonding pairs of electrons around the central atom. The four bonding pairs of electrons in tetrachloromethane repel each other equally, causing them to arrange themselves in a tetrahedral shape with the bond angle of 109.5°.
