Question

QUESTION 10 Identify the product for the following sigmatropic rearrangement. O A. 0 B. II O C.III O D.IV O E. None of the above are correct.

Answer 1

→ 40) sigmatropic rearrangement (3,3] sigmatropic 9.) option' C.) III is correct Siqmatrolic Claisen vue arrangement option D) IV is correct 2 8 ). Diels-Alder product- group attoched 19 II Он 개 Y OH to diene should + GL on be ERG (election releasing group) o and droup present at dienophile should be EWG. so option Bo) I is correct 7) most reactive dienophiles. y dienobhiles should contain Election with araw.al group on it and only į . contain Ewa. so ob tion C) mi is correct. Lo 5.) The Dielt Alder reaction is concerted reaction means cal All changes in bonding (bond making and bond breaking) occur simultaneously. Cs Sesnes posurect. 0 . mScanner

.6") Diene(s) only cisoid Diels-Alder reaction. form of diene reacts in transold form and cannot be converted to cisoid. - transoid form and cannot be converted to cisoid and cannot undergo Diels-Alder reaction 3. C.) Electrocylic reaction in which one new sigma bond is formed and one pi bond is lost so option Itive is correct ex ) ľ ho 2- pi bond one pirbond one new on-bond electrolydic (4h+2) toon → So option E) C&D is correct 1) lowest energy T-bonding molecular orbitical will have lowest possible value of nodal plane zero nadal so," option c) la is correct 0 000 plane 21) Pericyclic reactions - A) they are concerted reactions B.) proceed via a lylie . c) no intermediates are formed transition state s all above option are correct cs socans all of these are true.
