Statement - I : Xenon tetrafluoride molecule is denoted as AB4E4, where E is a lone pairStatement - II : All AB4 type molecules have no dipolemoment, because of symmetrical tetrahedral structure.

Statement I is false because the Xenon tetrafluoride molecule (XeF4) has a molecular formula of AB4E2, where E denotes two lone pairs on the central xenon atom.However, statement II is false. Although tetrahedral molecules with the AB4 formula, like methane (CH4), have no dipole moment because of their symmetrical structure, XeF4 does have a dipole moment because its lone pairs are arranged asymmetrically. This means that the electronegativity of the fluorine atoms in the molecule is not balanced, resulting in a net dipole moment.

Detailed Solution

Statement I is false because the Xenon tetrafluoride molecule (XeF₄) has a molecular formula of AB₄E₂, where E denotes two lone pairs on the central xenon atom.

However, statement II is false. Although tetrahedral molecules with the AB₄ formula, like methane (CH₄), have no dipole moment because of their symmetrical structure, XeF₄ does have a dipole moment because its lone pairs are arranged asymmetrically. This means that the electronegativity of the fluorine atoms in the molecule is not balanced, resulting in a net dipole moment.
