Chemistry - GOC Question with Solution | TestHub
Statement-I : Carbene form in reaction give cis syn as well anti addition with alkene.
Statement-II : Trans alkene give meso compound on addition with triplet carbene.
Options:
Answer:
Solution:
Statement-I is correct because triplet carbenes react via a two-step radical mechanism where bond rotation occurs before ring closure, resulting in both syn and anti addition products.
Statement-II is correct because when a symmetric trans-alkene undergoes triplet carbene addition, the anti-addition pathway (following bond rotation) yields a cis-cyclopropane. This resulting cis-cyclopropane derivative contains a plane of symmetry, making it a meso compound.
Since both statements are true, the correct choice is Option (A).
