why does the presence of lone pair electrons contribute to the polarity of a water molecule?\no they allow the bonds between oxygen and hydrogen to be single.\no they increase the partial positive charge on the oxygen atom.\no they prevent the atoms from forming a linear molecule.\no they counter the uneven pull on electrons between the atoms.

Answer

Brief Explanations:

The lone - pair electrons on the oxygen atom in a water molecule cause the molecule to have a bent shape instead of a linear one. A linear shape would result in the bond dipoles canceling out, making the molecule non - polar. The bent shape due to lone pairs leads to an uneven distribution of charge, contributing to the molecule's polarity.

Answer:

They prevent the atoms from forming a linear molecule.
