why the dipole moment in methane 0 - Chemistry - Chemical bonding and molecular structure

Question

why the dipole moment in methane 0?

na · Accepted Answer

The net dipole
of the molecule is equal to the vector sum of the dipole moments of
the various bonds present in the molecule The symmetrical
polyatomic molecules have zero dipole moment because the individual
dipole moments of the various bonds present in the molecule cancel
out each other

The methane
molecule has four polar bonds and all of these are oriented far
from each other in such a way that dipoles of individual bonds
cancel out and the net moment becomes
zero
