The C=C bond in 2-cyclohexenone produces an unusually strong signal. Explain using resonance structuresBased on the above resona
frosja888 [35]

Answer:

When two single single bonds separated by a double bond (e.g C=C-C=C or C=C-C=O in the case of 2-cyclohexenone), the effect of resonance among those there bonds will be observed.

Explanation:

Since the Oxygen atom has higher electronegativity, it will cause the electrons in the resonance bonds 'flow' toward the Oxygen atom, so that the C=C will 'lose' some electron. The signal read for that bond will be different from other alkene structure.

Attachment is the resonance structure of 2-cyclohexene.

What is the product of a reaction between a strong acid and a sulfite ion (which acts as a base)?
melamori03 [73]

SO_{2} is the product of a reaction between a strong acid and a sulfite ion (which acts as a base).

A chemical reaction in which an acid and a base interact quantitatively is known as neutralisation or neutralisation. By neutralising a reaction in water, surplus hydrogen or hydroxide ions are removed from the solution.

Despite being a weak base, the sulfite ion can hydrolyze to form basic solutions. The equilibria in an acidic solution are changed to create sulphurous acid, which leads to the development of SO2 gas. A colourless gas with a distinctive suffocating smell, sulphur dioxide.

The reaction mechanism is as follows;

SO_{3}^{2-} (aq) + H_{2} O(l) ⇒ HSO_{3} ^{-} (aq) + OH^{-} (aq)

HSO_{3} ^{-} (aq) + H_{2} O(l) ⇒ H_{2} SO_{3} (aq) + OH^{-} (aq)

H_{2} SO_{3} (aq) ⇒ H_{2} O (l) + SO_{2} (g)

Therefore, SO_{2} is the product of a reaction between a strong acid and a sulfite ion (which acts as a base).
