| Assertion: Oxidation number of carbon in \[C{{H}_{2}}O\] is zero. |
| Reason: \[C{{H}_{2}}O\] formaldehyde, is a covalent compound. |
A) If both assertion and reason are true and the reason is the correct explanation of the assertion.
B) If both assertion and reason are true but reason is not the correct explanation of the assertion.
C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
Correct Answer: B
Solution :
Both assertion and reason are true but reason is not the correct explanation of assertion. Oxidation number can be calculated using some rules. \[H\] is assigned +1 oxidation state and 0 has oxidation number ?2 \[\therefore \] O. No. of \[C\] in \[C{{H}_{2}}O\]: O. no. of \[C+2(+1)+(-2)=0\] \[\therefore \] O. No. of \[C=0\]
