Concept explainers
a) The H-Cl bond length is 136pm. What would be the dipole moment of H-Cl be if the molecule were 100% ionic, H+Cl-?
Interpretation:
Assuming H-Cl to be 100% ionic its dipole moment is to be calculated. Its bond length is given as 136pm.
Concept introduction:
Dipole moment is defined as, µ=Qxr
Where, Q=Magnitude of the charge developed at either end of the dipole.
R=The distance between the charges
It is expressed in Debyes (D). 1 D=3.336x10-30C.m
To determine:
The dipole moment of H-Cl assuming it to be 100% ionic. Its bond length is given as 136pm.
b) The actual dipole moment of H-Cl is 1.08 D. What is the percent ionic character of the H-Cl bond.
Interpretation:
Actual dipole moment of H-Cl is given as 1.08 D. Its percent ionic character is to be calculated.
Concept introduction:
Assuming H-Cl to be 100% ionic and knowing the bond length, the dipole moment of H-Cl can be calculated. From the calculated value and the actual value of dipole moments the percent of ionic character of H-Cl can be determined.
To determine:
The percent ionic character of the H-Cl bond, if its actual dipole moment is 1.08 D.

- Write all resonance structures of chlorobenzene, C6H5Cl, a molecule with the same cyclic structure as benzene. In all structures, keep the CCl bond as a single bond. Which resonance structures are the most important?arrow_forwardAcrylamide, H2C=CHCONH2, is a known neurotoxin and possible carcinogen. It was a shock to all consumers of potato chips and french fries a few years ago when it was found to occur in those products. (a) Sketch the molecular structure of acrylamide and identify all bond angles. (b) Indicate which carbon-carbon bond is the stronger of the two. (c) Is the molecule polar or nonpolar?

- Define the term lattice energy. Why, energetically, do ionic compounds form? Fig. 3-8 illustrates the energy changes involved in the formation of MgO(s) and NaF(s). Why is the lattice energy of MgO(s) so different from that of NaF(s)? The magnesium oxide is composed of Mg2+ and O2 ions. Energetically, why does Mg2+O2 form and not Mg+O? Why doesnt Mg3+O3 form?arrow_forward3-87 Consider the molecule boron trffluoride, BF3. (a) Write a Lewis structure for BF3. (b) Predict the FBF bond angles using the VSEPR model.
