Answer:
Explanation:
carbon in group 4A needs 4 more electrons to be stable
hydrogen in group 1A has one electron needs 1 more t o be stale
oxygen in group 6A has 6 and needs 2 more to be stable
They all obtain this by sharing electrons 8 around C &O, 2 around H
H : C: H

The osmotic pressure of the glucose solution is 21.49 atm.
From the question given above, the following data were obtained:
- Molarity (M) = 0.85 M
- Temperature (T) = 35 °C = 35 + 273 = 308 K
- Van't Hoff's factor (i) = 1 (non-electrolyte)
- Gas constant (R) = 0.0821 atm.L/Kmol
- Osmotic pressure (π) =?
π = iMRT
π = 1 × 0.85 × 0.0821 × 308
π = 21.49 atm
Therefore, the osmotic pressure is 21.49 atm

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.
