Question

Covalent bond and properties of covalent bond

Answer 1

Answer:

Explanation:

Covalent Bond:-These are the bonds formed by sharing the electrons not by donating them.

Properties:-  1.These are generally the poor conductor of electricity.

                    2.They have low melting and boiling point.

                    3.These are poor conductor of heat.

Answer 2

$\large{\underline{\underline{\mathfrak{Definition:-}}}}$

• The type of chemical bond formed by sharing of electrons are called Covalent bond.
• It is also called molecular bond.

$\large{\underline{\underline{\mathfrak{Properties\:of\: Covalent\:bond:-}}}}$

• It is strong bond but not more stronger than ionic covalent.
• It is poor conductor of heat and electricity.
• Has Low melting and boiling bond.
• Forms Brittle solids.
• Many covalent compounds have high vapor pressure, which makes them volatile and great as fuels.
• Covalent compounds usually have lower enthalpies of fusion and vaporization than ionic compounds.
• Covalent compounds tend to be more flammable than ionic compounds
• Methane, propane and gasoline are all covalent compounds that readily undergo combustion, producing energy as a bi-product.
