7)
Between N and H, N is more electronegative.
Dipole moment point to more electronegative element in the bond.
So, it will point from H to N
Answer: C
8)
Electronegativity difference less than 0.4 means non polar.
From 0.4 to 1.7 it forms polar covalent bond
Answer: D

A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...

POLARITY We've already talked about electronegativity and how to predict whether a bond is polar or nonpolar. For example: Pure covalent bond = sharing of electrons between two identical atoms (with the same electronegativity and no difference in charge) i.e. O2 Polar covalent bond = sharing of electrons between two or more different atoms with a difference in electronegativity. i.e. HCI Just as a bond can be polar or nonpolar, we can also classify an entire molecule as polar or...
