Answer:
In-F bond has the largest dipole moment.
Explanation:
Given the electronegativities:
Ge= 2.01
O= 3.44
H= 2.20
P= 2.19
In= 1.78
F= 3.98
B= 2.04
N= 3.04
The bond between Ge and O has an electronegativity difference:
ED= 3.44 - 2.01= 1.43
The bond between H and P has an electronegativity difference:
ED= 2.20 - 2.19= 0.01
The bond between In and F has an electronegativity difference:
ED= 3.98 - 1.78= 2.20
The bond between B and N has an electronegativity difference:
ED= 3.04 - 2.04= 1.00
As In-F bond has the largest electronegativity difference, this is the covalent bond with the largest dipole moment.
