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

  1. ABoth Statement-I and Statement-II are incorrect
  2. BStatement-I is incorrect but Statement-II is correct
  3. CBoth Statement-I and Statement-II are correct
  4. DStatement- I is correct but Statement-II is incorrect

Correct answer

D. Statement- I is correct but Statement-II is incorrect

Step-by-step 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.
