Animal skin is colloidal in nature and has positively charged particles. When they are soaked in tannin, their mutual coagulation takes place and, thus leather becomes hard after tanning

    Actually, ether has single oxygen atom as functional group -O- and its general formula is (R-O-R') in which the oxygen atom is sp3 hybridized and much more electronegative than the Carbon atoms of the alkyl groups R and R' even if they are same, so that there must be some more electronegativity and effect of lone pair of electrons at O-atom and it forms the polarity in the molecule.
