Temporary, as are ALL chemical bonds.
methanal, pentanal etc
Yes. Both of these atoms have at least one electron pair that is not always chemically bonded in any permanent way but can interact transiently with the positive charge of the nucleus of a chemically bonded hydrogen atom to form the temporary attractions designated as hydrogen bonds.
Because hydrogen is an element but hydrogen chloride is a polar compound so needs more energy to overcome the permanent dipole bonds. :)
There are no hydrogen bonds in HF.
It is not covalent, because it is the strongest type. The Correct answer is van der Waals.

Water molecules H2O consist of two hydrogens each joined to a central oxygen attom by covalent bonds. Water molecules stick to one another by hydrogen bonds, but these are not permanent bonds in the liquid.
oil is non-polar, so cannot form bonds with the water molecules - water molecules are polar, and hydrogen-bond to each other so for a substance to dissolve in water is must also be polar in order to form hydrogen bonds or permanent dipole - permanent dipole bonds.
Because in water hydrogen bonding is not permanent due to random motion where as in ice it is permanent also in ice k.e.is also lower
Because hydrogen is an element but hydrogen chloride is a polar compound so needs more energy to overcome the permanent dipole bonds. :)
Temporary and permanent are antonyms. Temporary means for a short period of time and permanent means for a long time/forever.
permanent is where you stay somewhere temporary is you stay there for a little while

A hydrogen acceptors for hydrogen bonds is nitrogen.
