Type of reaction involved in the initial step in the formation of bakelite
Options
- Aelectrophilic substitution
- Belectrophilic addition
- Cnucleophilic substitution
- Dnucleophilic addition
Correct answer
A. electrophilic substitution
Step-by-step solution
Bakelite It was the first plastic made from synthetic components. It is thermosetting phenol formaldehyde resin formed from a condensation reaction of phenol with formaldehyde. When the phenol is taken in excess and the reaction medium is made acidic, the product of the condensation reaction by electrophilic substitution mechanism obtained is acidic, whereas when the quantity of formaldehyde taken is more than that of phenol in the reacting mixture, and the reaction occurs in a basic medium, the condensation produc
