The correct option is C Polar covalent compound
C2H5OH has polar covalent C−O bond due to significant electronegativity difference between C andO. Similarly O−H bond is also polar covalent due to significant electronegativity difference between O and H atoms.
A covalent bond is formed by sharing of electrons. When this electron sharing is to an equal extent, the bond is non polar covalent. Otherwise the bond is polar covalent.
