Question

In which of the following reaction(s), hybridization of central atom changes as the product is formed?

• A. Ionisation of $H_{2}S{O}_3$
• B. Dimerisation of $BeC{l}_2$
• C. Attack of $HF$ on $B{F}_3$
• D. Hydrolysis of $POC{l}_3$

Answer 1

Answer: (B)

Dimerisation of $BeC{l}_2$

Solution:- (B) Dimerisation of $Be{Cl}_2$

Hybridisation of central atom, i.e., $Be$ in $Be{Cl}_2$ is $sp$ while the hybridisation of $Be$ in ${Be}_2{Cl}_4$ is $s{p}^2$.
