Vedclass · Answer

(B) In the dimer of $BH_3$,which is diborane $(B_2H_6)$,each Boron atom is bonded to four hydrogen atoms (two terminal and two bridging). Thus,the Boron atom undergoes $sp^3$ hybridisation.In the dimer of $BeH_2$ $(Be_2H_4)$,each Beryllium atom is bonded to three hydrogen atoms (one terminal and two bridging). Thus,the Beryllium atom undergoes $sp^2$ hybridisation.Therefore,the hybridisation states are $sp^3$ for $B$ in $B_2H_6$ and $sp^2$ for $Be$ in $Be_2H_4$.

The state of hybridisation of the central atom in the dimer of $BH_3$ and $BeH_2$ is
