Draw the principal organic product expected when 2-methylthiophene reacts with hno3. show minimized formal charges, if applicable.

2-Methyl-5-nitrothiophene  

Explanation:

The 2- and 5-positions of thiophene are the most susceptible to electrophilic aromatic substitution.

Thus, the major product from the reaction of 2-methylthiophene with HNO₃ in acetic acid is 2-methyl-5-nitrothiophene.

Hope the image of the frequency formula

1. i don't know.2. bitter taste, feels slippery, contains hydroxide or produces it in a solution.3. 104.i don't know.5. electrons.hope this somewhat!
