Who developed formaldehyde in the year 1868?

The correct answer is Hofmann, who is credited with the formal discovery of formaldehyde in 1868. Formaldehyde is a significant compound in various fields, including chemistry and funeral service, due to its use as a preservative and disinfectant. Hofmann's work was pivotal in organic chemistry, and his contributions laid the groundwork for many applications involving aldehydes, including formaldehyde's later use in embalming and preservation techniques in the funeral industry.

In contrast, the other individuals listed have made notable contributions in their respective fields, but they are not associated with the development of formaldehyde. Chemist Smith lacks specific recognition or established contributions regarding formaldehyde. Albert Einstein is renowned for his work in theoretical physics and the development of the theory of relativity, while Isaac Newton is best known for his laws of motion and universal gravitation, neither of which relates to formaldehyde. Understanding Hofmann’s contributions emphasizes the intersection of chemistry with practical applications in fields like funeral service, highlighting the importance of chemical advancements within the profession.
