Statement (A) $\mathrm{CO}_2$ has no dipole moment, whereas $\mathrm{SO}_2$ and $\mathrm{H}_2 \mathrm{O}$ have dipole moment. Statement (B) $\mathrm{SnCl}_2$ is ionic, whereas $\mathrm{SnCl}_4$ is covalent. Which of the following is correct?

• A

  Both (A) and (B) are not correct
• B

  (A) is correct but (B) is not correct
• Correct answer
  C

  Both (A) and (B) are correct
• D

  (A) is not correct but (B) is correct

Solution

$\mathrm{CO}_2$ is non-polar where as $\mathrm{SO}_2$ and $\mathrm{H}_2 \mathrm{O}$ are polar.
$\mathrm{SnCl}_2$ is ionic in aqueous medium whereas $\mathrm{SnCl}_4$ is covalent due to greater covalency of Sn.

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