Question

Which of the following is a property of ethanol?

• A. Ionic compound
• B. Noble gas
• C. Polar covalent compound
• D. Nonpolar covalent compound
• E. Metallic substance

Answer 1

The correct option is C Polar covalent compound

$C_2{H}_{5}OH$ has polar covalent $C-O$ bond due to significant electronegativity difference between $C$ and$O.$ 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.
