Black_prince [1.1K]

The statement that is an alloy is just another word for a chemical compound of fixed composition that is made of two or more metals is false.

An alloy refers to the mixture of the elements in which the parent element is the metal. An alloy is produced by the amalgamation of any element, that is, metal or non-metal to better the feature of the parent metal. The whole components in the alloy are combined to produce a mixture of fixed composition, but not a chemical compound, and it is not essential that the elements involved are metals. Thus, the mentioned statement is false.

As we know Benzene undergo Electrophilic Substitution Reactions. In case of substituted Benzene the incoming Electrophile is substituted either at Orto , Para position or Meta position. If the substituent is Electron Withdrawing in Nature then the Electrophile will go to meta position. When the substituent id Electron Donating in Nature then the incoming electrophile will be directed to ortho and para position.

In Benzenesulfonic Acid the substituent is Sulfonate (-SO₃H), it has a strong electron withdrawing effect. So on Nitration the Nitro group will be oriented to meta position and 3-nitrobenzenesulfonic acid is formed. On further Nitration 3-nitrobenzenesulfonic acid will be convert to 3,5-dinitrobenzenesulfonic acid because both Sulfonate and Nitrate groups are meta directing.
