Text Solution

Verified by Experts

The correct Answer is:
D
Condensation polymers are formed bny condensation of diols or diammine with dicarboxylic acids. Therefore ,
X may be : `-overset(O)overset("||")(C)-OR or -overset(O)overset(||)C-NH_(2) or -C-=N`
` - overset(O)overset(||)C-OR or underset(Delta)overset(H_(2)//Ni)to-CH_(2)OH`
`-overset(O)overset(||)C-NH_(2) overset(Br_(2)//NaOH)to-NH_(2)`
`-overset(O)overset(||)C-NH_(2) underset(Delta) overset(H_(2)//Ni)to-CH_(2)-NH_(2)`
`-C-= underset(Delta)overset(H_(2)//Ni)to-CH_(2)-NH_(2)`
