Consider 1:1 stoichiometric polymerisation of 1,4-diaminobutane with sebacoyl chloride.
(a) Write down a balanced chemical equation for the polymerization
(b) Name the polymer formed by this polymerization.
(c) Calculate the extent of reaction required to produce this polymer with a number-average molar mass of 8000.
(d) What would happen if you included 1,1,4,4-tetraaminobutane in the polymerisation so that the stoichiometric ratio was 1:2:4 tetraaminobutane:diaminobutane:sebacoyl chloride?

Nucleophilic addition reactions (i) Carbonyl compounds give nucleophilic addition reaction along with those reagents which on dissociation give electrophile also nucleophile.
Calculate how the internal energy stored in one O-H bond of H20 Consider the following chemical reaction H20(g)-->2H(g) + O(g) at 298.15 K and 1.00 Bar fH* [H(g)]=218.0 kJ/mole fH*
Physical methods for Non-volatile substances The non-volatile organic compound's molecular mass can be ascertained by noting either the elevation in boiling point of the solve
