Alcohols are commonly identified by their -oh hydroxyl group. however, what is the proper nomenclature when it is part of a compound? surely not every compound with a hydroxyl group is an alcohol. but, is the hydroxyl group itself considered an alcohol? or is it considered just a hydroxyl group? basically, when would you consider the -oh to be an alcohol compared to just being a plain ol' hydroxyl group? does it have to do with whether or not it forms aldehyde when it is oxidized?

I’m not too sure your question but an example of when seeing an -OH group wouldn’t mean it’s an alcohol is when you see a c double bonded to an O and then a single bond off the same C to and OH group which indicates a carboxylic acid rather than an alcohol. If your adding a halogen for example making it 1, chloro propan-3-ol in that case it’s still acting as an alcohol. Most of the time an OH group indicates an alcohol unless it’s a carboxylic axis as explained above. Hope this helps !

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
