Which of the following is false? a)Methane molecule is tetrahedral in...
Nickel tetrachloride (NiCl4) is not square planar in shape.
Explanation:
1. Methane molecule is tetrahedral in shape:
In a methane (CH4) molecule, carbon is bonded to four hydrogen atoms. These four bonds are arranged in a tetrahedral shape around the carbon atom. The carbon atom is at the center of the tetrahedron, and the hydrogen atoms are at the corners of the tetrahedron. So, option 'a' is true.
2. P2O5 is like two pyramids joined at their apices:
Phosphorus pentoxide (P2O5) consists of two phosphorus atoms and five oxygen atoms. The two phosphorus atoms are connected by an oxygen atom, forming a P-O-P bridge. The structure of P2O5 can be visualized as two pyramids joined at their apices. So, option 'b' is true.
3. Acetylene is linear:
Acetylene (C2H2) consists of two carbon atoms and two hydrogen atoms. The carbon-carbon triple bond in acetylene forms a linear structure. The two carbon atoms and the two hydrogen atoms are in a straight line, making the molecule linear. So, option 'd' is true.
4. Nickel tetrachloride is square planar in shape:
Nickel tetrachloride (NiCl4) is a coordination compound where nickel is bonded to four chlorine atoms. The electron configuration of nickel (Ni) is [Ar]4s23d8. It can form a complex by accepting two pairs of electrons from the chlorine atoms, resulting in a square planar geometry. The four chlorine atoms occupy the four corners of a square, with the nickel atom in the center. So, option 'c' is false.
The false statement is option 'c' - Nickel tetrachloride is square planar in shape.
