Q. Where was India's first petrochemical complex established?
Answer: Vadodara
Notes: Indian Petrochemicals Corporation Limited established the first petrochemical complex in Vadodara, Gujarat, in 1967. The site was chosen for its proximity to the Gujarat Refinery, which provided naphtha feedstock. Vadodara is known for polymer and chemical production. The complex spurred growth in India's petrochemical sector and remains operational. Haldia, Trombay, and Panipat became significant in the sector later but were established after Vadodara's complex.
