Solution 1
Step 1:
Step 2:
Step 3:
Solution 2
When formaldehyde and phenol react with a basic catalyst present, phenol-formaldehyde resins are created. Methylene bridges can develop at ortho, para, or both ortho and para locations during the process. This allows for the preparation of phenol-formaldehyde resin, often known as bakelite, a linear or cross-linked polymer.
Novolac is a linear polymer used in paints. Novolac undergoes cross-linking when heated with formaldehyde, forming an infusible solid mass known as Bakelite.
