Question

are water molecules semi rigid​

Answer 1

Answer:

Yes. But depends on structure. especially depends on bond angle.

Step-by-step explanation:

Due to the presence of these charges and the bent nature of the molecule, the center of the positive charge (half way between the two hydrogen atoms) does not coincide with the center of the negative charge (on the oxygen atom). In liquid water, this gives a molecular dipole moment from the center of negative charge to the center of positive charge, equivalent to a unit negative charge (that is, one electron) separated from a unit positive charge by 0.061 nm. The presence of this dipole moment in all water molecules causes its polar nature.

Hence, we can say that water molecule is semi rigid.
