A substance responsible for the sour taste of unripe orange is
The substance responsible for the sour taste of unripe orange is an organic acid. Organic acids are a class of compounds that have at least one carboxyl group (-COOH) in their molecular structure. The most common organic acid found in oranges is citric acid. When an orange is unripe, it contains more citric acid, giving it a sour taste. As the fruit ripens, the citric acid content decreases, and the fruit becomes sweeter. Therefore, the correct option is alkanoic acid.
