Actually both of the chapter contains some memory based questions . By the name of the topics the environmental chemistry provides some informations a learning about the daily in environmental basis chemistry. Same goes for the chemistry in everyday life. Those does not have that much weightage in JEE mains but if you are preparing for Neet you must should prepare all of those. If you are talking about your Neet preparing then I should tell that you should not complete in one day but you should prepare before hand.
