Statement-1 : Methyl orange is a weak acid 

Statement-2 : Benzenoid form of methyl orange is deeply coloured than quinonoid form 

(1) Statement-1 is correct and Statement-2 is wrong 

(2) Both the Statements-1 and Statement-2 are correct 

(3) Statement-1 is wrong and Statement-2 is correct 

(4) None of them

Answer 1

(1) Statement-1 is correct and Statement-2 is wrong 

Methyl orange is a weak acid. So, statement-1 is correct. In acidic medium, it exists in quinonoid form which is red in colour and in alkaline medium it exists in benzenoid form which is yellow in colour. Since red is more deeply coloured than yellow, Statement-2 is wrong.
