Answer:
B. HF
Explanation:
Hydrogen bonding is basically a bond between hydrogen and an electronegative element particularly the second-row elements nitrogen (N), oxygen (O), or fluorine (F).
option A.
Although oxygen is present, there are no O - H bond present. The oxygen is bonded to two carbon atoms hence hydrogen bonding is absent.
option B.
Hydrogen is bonded directly to Flourine. Hydrogen bond is present.
option C.
This is an organic compound, only covalent bonds are present in this molecule. No hydrogen bonds,
option D.
Lithium does snot have high electronegativity hence hydrogen bonding is absent.
The pH of the solution is used to estimate the acidic and the alkaline condition. The pH paper can be used to determine the conditions. The compound with pH 13.3 is basic.
<h3>What is pH?</h3>
The concentration of the hydrogen or the hydroxide ion in the water gives the estimate of the pH. The potential and the amount of hydrogen decide the acidic and the basic compound.
The pH scale ranges from 0-14 where the scale of 0-6 is acidic, 7 is neutral and 8-14 is basic. If the substance shows a pH of 13.3 then it will lie in the basic range.
Therefore, the compound with a pH of 13.3 is basic.

Answer:
Potassium has 20 neutrons.
Explanation:
The atomic number for potassium is 19, so that tells you that there are 19 protons in one atom of potassium.
Once you know the number of protons, you also know the number of electrons. There are the same number of protons and electrons in one atom, so there are also 19 electrons in one atom of potassium.
To find the number of neutrons, you need to work with the 'atomic weight' of the atom. This is also given in the table. The atomic weight for potassium is 39.10. Round this number to the nearest whole number, which would make it 39. This number is called the 'mass number.'
Subtract the number of protons from the mass number. For potassium, your equation would be 39 minus 19.
The resulting answer, 20, tells you the number of neutrons are in one atom.
