Question

how many single bond are present in ethyl alcohol

Answer 1

In a nonpolar covalent bond, the electronegativity values of the two atoms are not significantly different, so they equally share electrons. The electronegativity of hydrogen is 2.20, and the electronegativity of carbon is 2.55.

Answer 2

Hydrogen-Carbon Bonds

In a nonpolar covalent bond, the electronegativity values of the two atoms are not significantly different, so they equally share electrons. The electronegativity of hydrogen is 2.20, and the electronegativity of carbon is 2.55. The electronegativity difference of 0.35 between hydrogen and carbon is not strong enough to create a polar covalent bond.

Hydrogen-Oxygen and Carbon-Oxygen Bonds

In a polar covalent bond, the electronegativities of the atoms are sufficiently different enough to bias the shared electrons towards one of the two atoms. The electronegativity of oxygen is 3.44. The difference in electronegativity of the hydrogen-oxygen bond is 1.24. The difference in electronegativity of the carbon-oxygen bond is 0.89. In these bonds, the electrons are more attracted to the oxygen. As a result, this net polar force can lead to hydrogen bonds between two ethanol molecules or with a water molecule
