What happens when phenol is condensed with HCHO(formaldehyde) in presence of NaoH.
And please answer my previous organic chemistry question, it is opened for more than a week
Phenol and formaldehyde undergo condensation to give a polymer novolac (A) which on heating with formaldehyde gives bakelite (B) as a thermosetting polymer.
Sequence of the reaction can be written as
Structural difference between these two is that novolac is a linear polymer while bakelite is a cross linked polymer.
Here the initial reaction between phenol and formaldehyde is an example of aromatic electrophillic substitution.
Hope you understood
