Solved: A single bond between two carbons with different

Solution:

Here we have to show the direction of dipole moment by indicating arrow in the indicated bonds.

The given molecules are,

Dipole moment: Dipole moment arises due to the difference in electronegativity. It is denoted by arrow (→). The arrow will be directed towards an atom having higher electronegativity of atom having a higher bond moment.

 Step 1

In the given indicated bond, among the two C-C, the central C-atom (-CH=) is sp2 hybridized whereas the other C-atom (-CH3)is sp3 hybridized. It is known that greater the s-character, the bond moment will be increased. Because more s-character of sp2 C-atom the direction of the dipole moment will be towards the -CH= bond, as shown below,
