Question

8. Assign partial charges (at and ') to the appropriate atoms in each of the following polar bond S-F I-0 I-CI H-N

Answer 1

Polarity of bond depends on electronegativity difference of combining atoms. Electronegativity is a measure of tendency of an atom to attract shared pair of electron towards itself.

In bond, Atom having more electronegativity pulls shared pair of electrons towards itself , due to this it acquires some $\delta$ - charge and rest atom of bond acquires $\delta$ + charge.
