Answer:
If a solid line represents a covalent bond and a dotted line represents intermolecular attraction, which of the choices shows a hydrogen bond?
-N-------H-O-
-O------H-C-
-C-----H-F-
H-H
Of the options shown those that form hydrogen bonds are the following:
-N-------H-O-
-O------H-C-
Since they occur from the attraction in a hydrogen atom and an oxygen or nitrogen atom with a negative charge.
Explanation:
The hydrogen bridge or hydrogen bond force is the attractive electrostatic force between an electronegative atom and a hydrogen atom covalently bonded to another electronegative atom. It results from the formation of a charge-dipole force with a hydrogen atom attached to a nitrogen, oxygen or fluorine atom.
The hydrogen bond strength is located somewhere between a covalent bond and a Van der Waals force (dispersion force). This type of bonding occurs both in inorganic molecules such as water, and in organic molecules such as DNA.
How did the Heisenberg uncertainty principle contribute to the idea that electrons occupy "clouds" or "orbitals"? Because the exact position of the electron is not known,it must be assumed that the electron takes up the entire space in an orbital.
The three broad classes of elements are:
Metals
Metalloids
Nonmetals

I believe the correct answer from the choices listed above is the second option. Analgesics are the drugs that kill pain by blocking impulses at specific receptor sites of the brain and spinal cord. Analgesics<span> are drugs that alleviate pain without causing anesthesia. Hope this helps.</span>
