Concept explainers
(a)
Interpretation:
The charges attain by the given polar molecule are to be written.
Concept introduction:
Dipole moment arrows are drawn from the atom with less electronegativity to atom with more electronegativity.
Less electronegative gets partial positive charge and more electronegative atom gets partial negative charge.
(a)

Answer to Problem 57A
Oxygen is negative relative to carbon in
Explanation of Solution
Oxygen is more electronegative than carbon. So, arrow will be from carbon to oxygen. The partial charge is represented as follows:
Thus, oxygen is negative relative to C.
(b)
Interpretation:
The charges attain by the given polar molecule are to be written.
Concept introduction:
Dipole moment arrows are drawn from the atom with less electronegativity to atom with more electronegativity.
Less electronegative gets partial positive charge and more electronegative atom gets partial negative charge.
(b)

Answer to Problem 57A
Bromine is negative relative to Iodine in
Explanation of Solution
Bromine is more electronegative than iodine. So, arrow will be from iodine to bromine. The partial charges will be represented as follows:
Thus, bromine will be negative relative to I.
(c)
Interpretation:
The charges attain by the given polar molecule are to be written.
Concept introduction:
Dipole moment arrows are drawn from the atom with less electronegativity to atom with more electronegativity.
Less electronegative gets partial positive charge and more electronegative atom gets partial negative charge.
(c)

Answer to Problem 57A
Iodine is negative relative to Hydrogen in
Explanation of Solution
Iodine is more electronegative than hydrogen. So, arrow will be from hydrogen to iodine. The partial positive and negative charges will be represented as follows:
Here, I gets negative charge.
