Certain Quote by Jean-Baptiste Dumas
“In organic chemistry there exist certain types which are conserved even when, in place of hydrogen, equal volumes of chlorine, of bromine, etc. are introduced.”
About This Quote
Certain molecular structures remain unchanged despite substituting hydrogen with halogens, highlighting intrinsic stability patterns in organic compounds.
In simple terms: Substituting H with halogens preserves specific molecular types.

![“[Professor Bragg asserts that] In sodium chloride there appear to be no molecules represented by NaCl. The equality in number of sodium and chlorine atoms is arrived at by a chess-board pattern of these atoms; it is a result of geometry and not of a pairing-off of the atoms.” quote by Henry Edward Armstrong](https://sms4smile.com/quotes/img-quotes/bf5/henry-edward-armstrong-46976_atoms_professor-bragg-asserts-that-in-sodium-c_999839.jpg)
