Question

Given,$FeS{O_4}$ is a very good absorber for $NO$ , the new compound formed by this process is found to contain ____ unpaired electrons.
 A.$4$
 B.$5$
 C.$3$
 D.$6$

Answer 1

Hint: We have to know that, in science, an unpaired electron is an electron that possesses an orbital of an iota separately, instead of as a component of an electron pair. We need to know that each nuclear orbital of an iota (determined by the three quantum numbers n, l and m) has an ability to contain two electrons (electron pair) with inverse twists.

Complete answer:
We have to see that, as the development of electron sets is regularly vivaciously good, either as a synthetic bond or as a solitary pair, unpaired electrons are moderately extraordinary in science, on the grounds that a substance that conveys an unpaired electron is normally rather receptive. In natural science they normally just happen momentarily during a response on a substance called an extremist; nonetheless, they assume a significant part in clarifying response pathways.
When $FeS{O_4}$ is a very good absorber for $NO$ , the given compound colour is dark brown.
The balanced chemical equation is given,
$FeS{O_4} + NO \to FeS{O_4}.NO$
Where,
$NO$ donate one electron pair to one of the four unpaired electrons of $Fe$ .
$Fe$ has four unpaired electrons.
Therefore, the number of unpaired electrons is three.

Hence, the correct option is (C).

Note:
We have to see that ferrous sulfate shows up as a greenish or yellow-earthy colored glasslike strong. Thickness $15{\text{ lb/lady}}$ . We also know that it melts at $64^\circ C$ and loses the seven waters of hydration at $90^\circ C$ . The essential risk is the danger to the climate. Quick advances ought to be taken to restrict its spread to the climate.
