Mass number = protons + neutrons. 12 + 11 = 23.
Depending on the strictness of your teacher you can name it as either of the following:
2-methyl-propane or iso-propane
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.
Chunky peanut butter is a mixture which is NOT uniform throughout, so it is a heterogeneous mixture.
