Answer:
One or more number of species which have same number of atomic number but different mass number are called isotopes.
For example,
are the isotopes of hydrogen.
So here, the atomic number of each of these isotopes is 1 and have different mass number, that is, 1, 2, 3.
Answer:
Protons 4 or 5 are most acidic.
Explanation:
As mentioned there are four types of hydrogen in Hexane-2,4-dione.
The numbering are shown in the figure for your better understanding.
As shown in the figure if we remove the proton from carbon number 3 (protons number 4 or 5), it will result in formation of a carbanion. This carbanion is stabilized due to presence of -I group oxygen and there is possibility of resonance (as shown).
Thus protons 4 or 5 are most acidic.
