Concept explainers
(a)
Interpretation: Three resonance structures of naphthalene have to be drawn and the reason for why
Concept Introduction:
Resonance is an electron displacement effect for stabilizing a molecule through delocalization of bonding electrons in the pi orbital.
Delocalized electrons stabilize a compound. The extra stability gains from having delocalized electrons are called resonance stabilization or resonance energy.
Bond length: Bond distance or bond length is the average distance between nuclei of two bonded atoms in a molecule. It is a transferable property of a bond between atoms of fixed types
Double bonds: One sigma bond and one pi bond are together known as a double bond.
Bond length is inversely proportional to the bond order.
A higher bond order results in a shorter bond for a given pair of atoms.
(b)
Interpretation: Five resonance structures of phenanthrene have to be drawn and the bond that has a shorter bond length has to be predicted using resonance structures of phenanthrene.

- An open vessel containing water stands in a laboratory measuring 5.0 m x 5.0 m x 3.0 m at 25 °C ; the vapor pressure (vp) of water at this temperature is 3.2 kPa. When the system has come to equilibrium, what mass of water will be found in the air if there is no ventilation? Repeat the calculation for open vessels containing benzene (vp = 13.1 kPa) and mercury (vp = 0.23 Pa)arrow_forwardEvery chemist knows to ‘add acid to water with constant stirring’ when diluting a concentrated acid in order to keep the solution from spewing boiling acid all over the place. Explain how this one fact is enough to prove that strong acids and water do not form ideal solutions.arrow_forwardThe predominant components of our atmosphere are N₂, O₂, and Ar in the following mole fractions: χN2 = 0.780, χO2 = 0.21, χAr = 0.01.
