what aspect of water is the source of cohesion?\nacidity\nsmall size\npartial charge\nquestion 2\nwhich of these covalent bonds is polar, based on the electronegativity of the elements?\nc - h\nc - o

Answer

Brief Explanations:

  1. Water cohesion is due to hydrogen - bonding which is a result of the partial charges on water molecules (oxygen is partially negative and hydrogen is partially positive). Acidity and small size are not related to cohesion.
  2. A polar covalent bond has an unequal sharing of electrons due to a significant electronegativity difference between the atoms. The electronegativity of oxygen is much higher than that of carbon, creating a polar C - O bond. The electronegativity difference between carbon and hydrogen is relatively small, making the C - H bond less polar.

Answer:

Question 1: partial charge Question 2: C - O
