Explanation:
Percent composition is percentage by the mass of element present in the compound.
The formula for chromium(III) nitrate is
Molar mass of chromium(III) nitrate = 238.011 g/mol
1 mole of chromium(III) nitrate contains 9 moles of oxygen
Molar mass of oxygen = 16 g/mol
So, Mass= Molar mass*Moles = 16*9 g = 144 g
2-methyl-3-hexyn-2-ol can be prepared from Acetylene by treating Acetylene with <span>NaNH</span>₂<span> followed by CH</span>₃<span>CH</span>₂<span>Br, then treating the intermediate with NaNH</span>₂<span> followed by acetone and then doing aqueous workup. NaNH</span>₂ acts as base and abstracts proton from acetylene as the terminal alkynes are acidic in nature. While acetone on reduction gives tertiary alcohol.
