Polar molecule consists of bond dipoles, which do no longer cancel each different. Therefore, CH3COOCH2CH3 incorporates polar bonds(CO and CO) wherein their bond dipoles do no longer cancel each other. Hence, ethyl acetate is a polar compound.
NB: Relative electronegativity determines whether or not a compound is a polar or no longer. When the electronegativities between the two atoms are not identical then electrons aren't distributed similarly amongst them. Partial ionic costs shape among them consequently ensuing in polar bonds. Though,we can say that there are compounds with polar bonds but are nonpolar. Hence, cancellation of bond dipoles additionally determines whether a compound is a polar or not. The cancellation of bond dipoles relies upon at the stereochemistry and also the orientation of polar bonds gift.
