Which of the Following is Responsible for the Cohesion of Water

Question

Which of the following is responsible for the cohesion of water molecules?
A) hydrogen bonds between the oxygen atoms of a water molecule and cellulose in a vessel cell
B) covalent bonds between the hydrogen atoms of two adjacent water molecules
C) hydrogen bonds between the oxygen atom of one water molecule and a hydrogen atom of another water molecule
D) covalent bonds between the oxygen atom of one water molecule and a hydrogen atom of another water molecule
E) low concentrations of charged solutes in the fluid

Accepted Answer

Hydrogen bonds between the oxygen atom of one water molecule and a hydrogen atom of another water molecule are responsible for the cohesion of water molecules. These hydrogen bonds form due to the polarity of the water molecule, with the oxygen atom being slightly negative and the hydrogen atoms being slightly positive. This polarity allows for the attraction between adjacent water molecules, leading to the cohesive properties of water.
