Vedclass · Answer

(B) The given conversion involves two steps: $1$. The reduction of an alkyne to a cis-alkene. This is achieved using Lindlar's catalyst $(H_2/Pd-CaCO_3)$. $2$. The cyclopropanation of the alkene to form a dibromocyclopropane derivative. This is achieved by the addition of dibromocarbene $(:CBr_2)$,which is generated in situ from bromoform $(CHBr_3)$ and a strong base $(NaOH)$. Therefore,the correct sequence of reagents is $H_2/Pd-CaCO_3$ followed by $CHBr_3/NaOH$.

Identify the reagents used for the following conversion in the correct order.
