According to the vsepr model, a molecule with the general formula ab4 with two lone pairs on the central atom will have a _____ molecular geometry.
Answers
Answer:
According to the VSEPR model, a molecule with the general formula AB4 with two lone pairs on the central atom will have a tetrahedral molecular geometry.
Explanation:
This geometry involves a central atom that is situated at the center of four other atoms which are found at the corner of a tetrahedron. It has a hybridization of sp3. When the four atoms in the corner are the same element, then the bond angles would measure 109.5 degrees. This geometry would lead to a non polar substance. Molecules which takes the shape of tetrahedral are known to be chiral. Examples are methane, ammonium ion, phosphate ion and carbon tetrachloride.
