Answer : The crown is not made of pure (100%) gold.
Explanation :
Formula used :
where,
= apparent weight of the crown in water = 4.50 N
= actual weight = 5.00 N
= density of water = 
= density of crown = ?
Now put all the given values in the above formula, we get:
Density of crown < Density of gold
Thus, the crown is not made of pure (100%) gold.
The reaction of 2 methylbutane with chlorine yield 5 monochloro derivative. Methylbutane has four carbon atoms which react with chlorine. The carbon with antibonding will be chiral and it will react with chlorine. there will be four difference group around chiral carbon hence it will have stereoisomers.
