Polarity of Molecules

Lisa had prepared X-molecule inside YG laboratory. X molecule has an electronegative difference of 0.327, what is the type of chemical bond present on X molecule?

•  Ionic

• Hydrogen

• Polar Covalent

• Nonpolar Covalent

Why is water has a bent molecular geometry instead of a linear one?

• Due to the attraction of 2 lone pairs of Oxygen

• Due to the repulsion force of 2 lone pairs of Oxygen
