Which situation describes a hydrogen bond? view available hint(s) which situation describes a hydrogen bond? the h atom of a water molecule interacts with the o lone-pair electrons of a neighboring water molecule. the h atom of a water molecule covalently bonds to the o in the same molecule. the h bonds to na in nah. h+ acts as a lewis acid.

Option (a) is the correct answer.

Explanation:

Hydrogen bonding is defined as a bonding which exists between a hydrogen atom and an electronegative atom like O, N and F.

But when H atom of a water molecule covalently bonds to the O in the same molecule then it will be a covalent bond and not a hydrogen bond.

As H atom of a water molecule has a partial positive charge so, it will interact with the O lone-pair electrons of a neighboring water molecule and then it will lead to the formation of a hydrogen bond.

Thus, we can conclude that the situation H atom of a water molecule interacts with the O lone-pair electrons of a neighboring water molecule, describes a hydrogen bond.

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
