If a molecule has four hybrid sp3 orbitals, it can be concluded that the molecule has a
a: trigonal planar molecular geometry.
b: trigonal planar electron domain geometry.
c: tetrahedral molecular geometry.
d: tetrahedral electron domain geometry.

C: tetrahedral molecular geometry

Explanation: The number of hybrid orbitals are 4 that means the hybridization will be and the electronic geometry of the molecule will be tetrahedral.

But if one or more positions are occupied by lone pair of electrons, the repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be trigonal pyramidal or bent.

For Example : has nitrogen in hybridization but as only three hydrogen are present, fourth position will be occupied by lone pair and molecular geometry will be trigonal pyramidal.

has oxygen in hybridization but as only two hydrogen are present, third and fourth position will be occupied by lone pair and molecular geometry will be bent.

water   molecules stay close to each other through cohesion, the collective action of hydrogen bonds between water molecules. cohesion plants draw water upwards from the root through the stem's transport tubes (xylem) to the leaf. this transport occurs even in large trees and against gravity. transpiration, evaporation of water from plant leaves, creates a tension on water molecules being pulled up from the stem and roots.

water also has high (the attraction of one substance to another) properties because of its polar nature. adhesion of water molecules to plant cell walls counteract gravity while water is transported from roots to leaves.

water exhibits a very high surface tension when compared to other liquids. surface tension is a property of a liquid that holds the surface together and allows it to resist an external force. by capillary action, the water forms concave menisci inside the pores. the high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants.

thus, cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

therefore, option d) is the correct answer.
