Question

The state of hybridisation of central atoms in dimer of $B{H}_3$ and $Be{H}_2$ .

• A. $s{p}^2,s{p}^2$
• B. $s{p}^3,s{p}^2$
• C. $s{p}^3,s{p}^3$
• D. $s{p}^2,s{p}^3$

Answer 1

Answer: (B)

The state of hybridisation of central atom in dimer of $B{H}_3$ and $Be{H}_2$ are $s{p}^3,s{p}^2$
$2B{H}_3\to B_2{H}_6$

$2Be{H}_2\to B{e}_2{H}_4$
