Given below are two statements:
Statement-I : Methyl orange is a weak acid.
Statement-II : The benzenoid form of methyl orange is more intense/deeply coloured than the quinonoid form.
In the light of the above statement, choose the most appropriate answer from the options given below:

Options:

Answer:
D
Solution:

Methyl orange is a weak acid. Additionally, in acidic conditions, methyl orange exists in the quinonoid form, which is red in color. In alkaline conditions, it exists in the benzenoid form, which is yellow in color. Since red is more deeply coloured than yellow, Statement-2 is wrong.
