C2H4 Non-Polarity and Structure

The video tutorial explains the polarity of C2H4, highlighting its symmetrical structure, which results in it being a non-polar molecule. The instructor uses the Valence Shell Electron Pair Repulsion (VSEPR) theory to demonstrate how the hydrogen atoms spread out to maintain symmetry, confirming the absence of any positive or negative poles. The conclusion reinforces that C2H4 is non-polar due to its symmetrical nature.

What characteristic of C2H4's Lewis structure contributes to its non-polarity?

• Asymmetrical distribution of atoms

• Unequal sharing of electrons

• Presence of a net dipole moment

• Symmetrical arrangement of atoms

According to VSEPR theory, how do the hydrogen atoms in C2H4 behave?

• They form a linear arrangement

• They cluster together to form a pole

• They spread out to minimize repulsion

• They create a net dipole moment

What is the main reason C2H4 is considered non-polar?

• It has a high electronegativity difference

• It has a symmetrical structure with no poles

• It contains a polar covalent bond

• It has an uneven distribution of electrons

What does the absence of a positive or negative pole in C2H4 indicate?

• The molecule is ionic

• The molecule is polar

• The molecule has a net dipole moment

• The molecule is non-polar
