Answer:
The nitro group is an ambident group and is capable of getting attached to carbon chain through nitrogen. as well as through oxygen (-O - N = O) atom. The compound in which the -NO2 group is linked to the alkyl or aryl group through oxygen atom are called nitrites
<span>The percent composition of s in the compound is 44.4%.
</span>
No. of grams of ca = 15
no. of grams of S = 12
<span>percent composition of s in the compound = 12/(15 + 12) x 100
= 12/27 x 100
= 0.44 x 100
= 44.4%</span>
