Functional group is a topic in organic chemistry that consistently garners a high level of interest, as evidenced by its consistently high search volume and steady trend of popularity over the past few years. The associated search terms indicate that people are curious about the specific types and characteristics of functional groups, particularly in relation to esters, amines, aldehydes, and ethers. This suggests that people are interested in understanding the chemical properties and reactions of different functional groups, and likely have a practical use for this knowledge in fields such as drug design and materials science. The low competition and CPC for many of these search terms also suggests that there is potential for content creators and business owners to target this niche audience. Overall, the sustained interest and relatively low competition for functional group-related search terms suggests that this topic will continue to be relevant and important in the field of organic chemistry.
