Answer:

The answer to your question is:

atomic number (Z): 6

mass number (A) : 13

Explanation:

Carbon has an atomic number of 6 and a mass number of 12,

Mass number = # protons + # neutrons

12 = 6 + # neutrons

#neutrons = 12 - 6 = 6

For the carbon isotope the atomic number does not change is still 6

13 = 6 + # neutrons

# neutrons = 13 - 6

# neutrons = 7

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

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.
