Q11 / 160 · AP EAMCET 2020 (22 Sep Shift 2) · Chemistry

The isostructural molecules among $\mathrm{CO}_2, \mathrm{SiO}_2, \mathrm{SO}_2, \mathrm{TeO}_2,\left[\mathrm{NO}_2\right]^{+}$are

  • A
    $\mathrm{CO}_2, \mathrm{SO}_2, \mathrm{TeO}_2$
  • B
    $\mathrm{CO}_2, \mathrm{SiO}_2,\left[\mathrm{NO}_2\right]^{+}$
  • Correct answer
    C
    $\mathrm{CO}_2,\left[\mathrm{NO}_2\right]^{+}$
  • D
    $\mathrm{SO}_2, \mathrm{TeO}_2$

Solution

In $\mathrm{CO}_2$ and $\left[\mathrm{NO}_2\right]^{+}$, the central atom are $s p$-hybridised. Hence, they have linear structure. Thus, correct option is (3).

Hence, the correct answer is option: 'C'.
