Question

With which of the given pairs CO$_2$ resembles in structure?

• A. $HgCl_2,C_2H_2$
• B. $HgCl_2,SnCl_4$
• C. $C_2H_2 ,NO_2$
• D. $N_2O \, and \, NO_2$

Answer 1

Answer: (A)

$HgCl_2,C_2H_2$

Answer 2

CO2 is linear in structure.

(A) HgCI2 and HC $\equiv$ CH(C2H2) both are linear in structure.
(B) HgCl2 is Iinear but SnCl4 is tetrahedral in structure.
(C) C2H2 is linear but NO2 is bent.
(D) N2O is linear but NO2 is bent in structure.

So, the correct answer is (A): HgCl2​, C2​H2​
