1. Time remalning: 1:28 8. Which of the following statements about kineticvs. tfermodynamic
products is true? O The product that is formed faster is the thermodynamic product The kinetic
product predominates at low temperature. O The product that predominates at equilibrium is the
kinetic product. O The thermodynamic product is less stable. Ask your instructor a question
Solution
option B is correct
explanation:
The reaction that forms the kinetic product are called kineticaly controlled reactions and the
reactions that form the thermodynamic product are called thermodynamicaly controlled reactions
In the kineticaly controlled reactions the reactions are carried out at sufficiently mild conditions
that is at lower temperature . so there is a enough energy to cross the energy barrier to form the
intermediate which is converted to product. As the reaction is carried at relatively low
temperature the products cant be reversed so reaction is irreversable and product formation
occurs fastly.
In the thermodynamically controlled reactions the reaction is carried out at sufficiently vigorous
conditions that is at higher temperature . So the products formed can be reversed to
intermediate (as at higher temperature) which can rearrange to a more stable one. So forms the
more stable product . As the reaction is reversible i t is also called as equilibrium control
