So we have given here bromine molecule and carbon tetragloryte molecule ccl4.
00:05
So now first of all we have to determine that what kind of molecules these are, are they polar or nonpolar.
00:12
So considering br2 that can be represented as br bonded with br, okay two br atoms are bonded together.
00:26
So that are bromine atoms.
00:29
Now, both have same electronegativity, there is no electronegativity difference ok.
00:36
So, since there is no electronegativity difference, no dipole moment ok.
01:28
Ok.
01:31
And hence br2 bromine molecule is non polar ok.
01:53
So, hence we got to know that here this bromine molecule is non polar because there is no electron negativity difference and hence there is no dipole moment, there is no asymmetrical distribution of charge okay then we have given ccl4 or carbon tetra chloride that can be represented as carbon bonded to four chlorine atoms in a tetrahedral manner like this now here chlorine is more electronegative than carbon okay so yes there is partial negative charge over chlorine atoms and the carbon has partial positive charge charge, but here actually let me draw it again...
