Concept explainers
(a)
Interpretation:
Out of the three isomers of dichlorobenzene, the polar forms have to be identified.
Concept Introduction:
VSEPR model is useful tool to determine shapes as well as properties such as polarity of molecules.
The extent of polarity is quantitatively expressed as dipole moment. It is defined as product of charges of two bonded atoms and the separation between them. The electronegativity difference decides the direction of dipole moment. It is indicated by an arrow head from positive end towards negative end.
For complex molecules, the shape must be determined prior to determination of individual dipoles. Thus shape is governed by the VSEPR model.
(b)
Interpretation:
The isomer with largest dipole moment has to be identified.
Concept Introduction:
Refer to part (a).

- Consider the reaction of a propanoate ester with hydroxide ion shown below. A series of four alcohol leaving groups were tested to determine which would be the best leaving group. Based on the pKa values of the alcohols, predict which alcohol would produce the fastest hydrolysis reaction. HO FOR A Alcohol I, pKa =16.0 B Alcohol II, pKa =10.0 C Alcohol III, pKa = 7.2 + ROH D Alcohol IV, pKa = 6.6arrow_forwardCurved arrows are used to illustrate the flow of electrons.
