Water molecule is very polar. Polar end of molecule attracts opposite charges on another water molecule (acts like magnet). How will you explain this property of water with reference to upward movement of water? Comment on the upward movement of water given the intermolecular hydrogen bonding in water.

Ans.

Water is known to be a highly polar molecule; the hydrogen atom is positive by the oxygen atom is negative, which creates the polar charge. Therefore the two atoms attract each other and create a force which is one of the major determinants for or the surface tension that is formed on any liquid, complemented by certain intermolecular forces. This helps the plant to absorb water from the soil through the root and the xylem, eventually reaching the leaves. The forces of cohesion and adhesion help molecules to stick to each other as well as a surface and enable it to be transported in a continuous fashion. All these factors help and assist the ascent of sap.
