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.

The concentration of hydronium ions is greater than 1 × 10–7 for basic solutions. True False

Nataly [62]

Answer : The given statement is, false.

Explanation :

Ionic product of water : It is defined as the product of the concentration of hydrogen ion and the concentration of hydroxide ion.

The mathematical expression will be,

$[H^+][OH^-]=10^{-14}$

When the concentration of hydrogen ion and hydroxide ion are equal then the solution is neutral and the value will be, $1\times 10^{-7}$ . And the pH of the solution is, 7.

When the concentration of hydrogen ion is greater than $1\times 10^{-7}$ then the solution is acidic in nature. And the pH of the solution is, less than 7.

When the concentration of hydrogen ion is less than $1\times 10^{-7}$ then the solution is basic in nature. And the pH of the solution is, greater than 7.

Hence, the given statement is false.
