which of the following statements is true about the strength of the hydrogen bonding in h f and h2o?
hf ≥ h2o because δ − on o in the h o bond is greater than δ − on f in the h f bond.
h f < h2o because the radius of h in h o is shorter than the radius of h in h f.
h f < h2o because f in h f has an extra lone pair compared with o in h2o.
h f ≥ h2o because the h f bond is more polar than the h o bond.

HF ≥ H₂O because the HF bond is more polar than the OH bond.

Explanation:

Electrons in the bond will not be shared equally. Hydrogen electronegativity value is 2,1 but Fluorine is 4, so electrons in the covalent bond will be more attracted to Fluorine. The electron cloud will be more distorted towards Fluorine.

I hope this is correct, and as always, I am joyous to assist anyone at any time.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
