I hope i helped =)
the answer is true the first one
<h3>Answer:</h3>
Water molecules have a polarity, which allows them to be electrically attracted to other water molecules and other polar molecules by weak chemical bonds known as <u>Hydrogen Bond</u>.
<h3>Explanation:</h3>
Hydrogen Bond Interactions are those interactions which are formed between a <em>partial +ive</em> hydrogen atom bonded directly to most electronegative atoms (i.e. Fluorine, Oxygen and Nitrogen) of one molecule interacts with the <em>partial -ive</em> most electronegative atom of another molecule. These interactions are considered the strongest intermolecular interactions and are responsible for many stronger physical properties of water like, boiling point, viscosity, solubility e.t.c.
Attached figure shows the hydrogen bond interactions (green dashed lines) between water molecules. The partial charges are shown in red color.
