please expalin in Detail

4. The reaction of 2-bromobutane A with sodium hydroxide under heat produced three different products buen cis-but ene and trans but 2-ene Dj.It turns out that is produced in the largest proportion followed by C the which can be explained in terms of thermodynamic stability NOH Describe how the products can be rigorously comoared thermodynamically and drawn portabeled en diagram art of that explanation you do not need to include any quantitative information is your 5 points Explain the factors that cause the products to be produced in different p ortions

Readent Porducts Reaction G hese, activation energy of f is highest means it is least followed by C & . highest concentration of D is found due to lowest activation Energy ② As D is trans product, hence, least hinderd product is formed I 38 is least favoured due to attack from { hydrogen. ① C&D are more than B due to Symmetry in these products. where my B is assymetrie. - ③D is farvoured most due to stablity of fans product due to csleast.
