(a)
Interpretation:
The dipole moment arrow is to be drawn for the given C-F bond.
Concept introduction:
Dipole moment arrows are drawn from the atom with less electronegativity to atom with more electronegativity.
(a)

Answer to Problem 17A
Explanation of Solution
Fluorine is more electronegative than carbon because left to right electronegativity increases. So, arrow will be from carbon to fluorine.
(b)
Interpretation:
The dipole moment arrow is to be drawn for the given Si-C bond.
Concept introduction:
Dipole moment arrows are drawn from the atom with less electronegativity to atom with more electronegativity.
(b)

Answer to Problem 17A
Explanation of Solution
Carbon is more electronegative than silicon because down the group electronegativity decreases. So, arrow will be from carbon to silicon.
(c)
Interpretation:
The dipole moment arrow is to be drawn for the C-O bond.
Concept introduction:
Dipole moment arrows are drawn from the atom with less electronegativity to atom with more electronegativity.
(c)

Answer to Problem 17A
Explanation of Solution
Oxygen is more electronegative than carbon because left to right electronegativity increases. So, arrow will be from carbon to oxygen.
(d)
Interpretation:
The dipole moment arrow is to be drawn for the given B-C bond.
Concept introduction:
Dipole moment arrows are drawn from the atom with less electronegativity to atom with more electronegativity.
(d)

Answer to Problem 17A
Explanation of Solution
Carbon is more electronegative than boron because left to right electronegativity increases. So, arrow will be from carbon to boron.
