Question

Determine if the following statements are true or false. _____(13)_____Conjugated dienes react more quickly than isolated alkenes and can be reacted with selectively. _____(14)_____ The thermodynamic product is the fastest formed product. _____(15)_____The thermodynamic product and kinetic product are always different products for all reaction types. _____(16)_____ Conjugated pi systems still follow Markovnikov's rule so as to form the most stable intermediate cation. _____(17)_____Extended pi systems become increasingly reactive with electrophiles as the energy of the intermediate lowers. _____(18)_____Extended pi systems become increasingly thermodynamically stable as the extra orbitals lower the energy of bonding electrons. _____(19)_____Conjugation makes molecules high energy and unstable.

Answer 1

13) False because conjugated dienes will be stabilised by resonance structures

14) True the thermodynamic product is the fastest formed product.

15) False The thermodynamic product and kinetic product may be same or different both can be possible

16) True Conjugate pi systems still follow markovnikov's rule so as to form stable intermediate cation

17) True Extended pi systems become increasingly reactive with electrophiles as the energy of the intermediate lowers.

19) False Conjugation makes releasing of energy hence it is more stable
