CHXI11:THE P-BLOCK ELEMENTS

316161 When oxalic acid is heated with concentrated \(\mathrm{H}_{2} \mathrm{SO}_{4}\) it produces :

1 \(\mathrm{CO}, \mathrm{CO}_{2}\)
2 \(\mathrm{SO}_{2}\) and \(\mathrm{CO}_{2}\)
3 \(\mathrm{CO}\) and \(\mathrm{SO}_{3}\)
4 None of these

316162 Read Assertion and Reason carefully and mark correct option.
Assertion :
Carbon forms two important oxides -CO and \(\mathrm{CO}_{2} . \mathrm{CO}\) is neutral whereas \(\mathrm{CO}_{2}\) is acidic in nature.
Reason :
\(\mathrm{CO}_{2}\) can combine with water in a limited way to form carbonic acid, while CO is sparingly soluble in water.

1 Assertion is not correct but Reason is correct.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.
3 Both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
4 Assertion is correct but Reason is not correct.
