Polar vs Nonpolar Compounds Quiz

Water has a symmetrical shape, which allows for even distribution of charge.

Water has a bent shape and a difference in electronegativity between hydrogen and oxygen, leading to an uneven distribution of charge.

Water molecules are held together by ionic bonds, which create polarity.

Water is a nonpolar molecule because it has no net dipole moment.

The molecule is linear, and the dipoles cancel each other out.

The molecule is bent, causing the dipoles to reinforce each other.

The molecule has a high electronegativity difference, making it nonpolar.

The molecule is tetrahedral, leading to a nonpolar nature.

Ammonia has hydrogen bonding due to the presence of nitrogen, while methane only has London dispersion forces.

Ammonia is a larger molecule, leading to stronger London dispersion forces.

Methane has a higher electronegativity difference, leading to stronger dipole-dipole interactions.

Methane forms hydrogen bonds, while ammonia does not.

$$CCl_4$$ ; it is polar because of its tetrahedral shape.

$$CH_3Cl$$ ; it is polar due to the difference in electronegativity between carbon and chlorine.

$$BF_3$$ ; it is polar because of its trigonal planar shape.

$$N_2$$ ; it is polar due to the triple bond between nitrogen atoms.

$$HF$$ has a larger atomic radius than $$HCl$$ , leading to greater polarity.

$$HF$$ has a higher electronegativity difference between hydrogen and fluorine compared to hydrogen and chlorine.

$$HF$$ is a larger molecule, which increases its polarity.

$$HF$$ has a linear shape, while $$HCl$$ does not.

$$CO_2$$ ; because it is a linear molecule.

$$H_2S$$ ; because it has a bent shape and a significant electronegativity difference.

$$CH_4$$ ; because it is a tetrahedral molecule.

$$N_2$$ ; because it has a triple bond.

$$HI$$ has weaker London dispersion forces compared to $$HF$$ .

$$HI$$ has dipole-dipole interactions compared to the stronger hydrogen bonding interactions of $$HF$$ .

$$HI$$ has weaker dipole-dipole interactions compared to $$HF$$ .

$$HI$$ has a lower molecular weight compared to $$HF$$ .

The molecule is tetrahedral, and the dipoles cancel out due to symmetry.

The molecule is linear, leading to nonpolarity.

The molecule has a high electronegativity difference, making it nonpolar.

The molecule is planar, causing the dipoles to cancel out.
