The above structure exhibits three rings. Identify which of the rings are aromatic. Enter the numbers in ascending order separated by a comma (e. g. 1,2,3). Identify which lone pairs are participating in resonance (in aromatic rings). One lone pair on each of the nitrogen atoms and one lone pair on each of the OH groups. One lone pair on the sulfur atom. One lone pair on the sulfur atom and one lone pair on the OH group. One lone pair on each of the sulfur atoms and one lone pair on each of the OH groups

The aromatic ringsare the number 1 and 2.

Identify which lone pairs are participating in resonance (in aromatic rings).

Explanation:

For a compound to be aromatic it has to comply with Hückel's Rule, which says that the quantity of electrons in the pi orbitals, has to be a multiple of

4n + 2

for n = 0, 1, 2, 3.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.
