Question

Which of the following conversions does not represent the process of dimerization ?

• A. $Be{H}_2\to Be{H}_2$ (soild)
• B. $S_2{O}_2^{2-}\to S_4{O}_2^{2-}$
• C. $NO\to N_2{O}_2$
• D. $Cl{O}_3\to C{l}_2{O}_6$

Answer 1

Answer: (A), (B)

The correct options are
A $Be{H}_2\to Be{H}_2$ (soild)
B $S_2{O}_2^{2-}\to S_4{O}_2^{2-}$

A compound formed by the union of two radicals or two molecules of a simpler compound, specially a polymer formed from two molecules of a monomer, and this process is called dimerization.

A) $Be{H}_2\to Be{H}_2$ (soild) not dimer (Dimer is $B{e}_2{H}_4$)

B) $S_2{O}_2^{2-}\to S_4{O}_2^{2-}$ not dimer (Dimer is $S_4{O}_4^{2-}$)

C) $NO\to N_2{O}_2$ is Dimer.

D) $Cl{O}_3\to C{l}_2{O}_6$ is Dimer.

Hence options A,B are correct.
