Answer

Brief Explanations:

Cohesion in water is due to hydrogen - bonding which is a result of the partial charges on the atoms (oxygen has partial negative and hydrogen has partial positive charges) in a water molecule. Polar covalent bonds occur when there is a difference in electronegativity between the bonding atoms.

Answer:

Question 1: C. partial charge Question 2: (No options provided for Question 2 in the text, so unable to answer fully for this part. But conceptually, a polar covalent bond has a difference in electronegativity between the two atoms involved.)
