Answer: Option (3) is the correct answer.
Explanation:
Molecular substances are the substances which have two or more different atoms attached together.
Molecular substances have weak intermolecular forces of attraction thus, they have low melting and boiling point.
They have poor electrical conductivity as the bond formation in molecular compounds is covalent. Therefore, they also have poor heat conductivity.
Hence, out of the given options low melting point is the characteristic property of molecular substances.
Answer is: 3) low melting point.
Molecular substances are usually gases and liquids with low melting point.
The melting point depends on the strength of the intermolecular forces.
Intermolecular forces are the forces between molecules.
Molecular substances have bad heat conductivity and electrical conductivity.
Molecular substances are bonded with covalent bonds.

Answer : The oxidation number of nitrogen (N) is, (-3)
Explanation :
Oxidation number : It represent the number of electrons lost or gained by the atoms of an element in a compound.
Oxidation numbers are generally written with the sign (+) and (-) first and then the magnitude.
When the atoms are present in their elemental state then the oxidation number will be zero.
Rules for Oxidation Numbers :
The oxidation number of a free element is always zero.
The oxidation number of a monatomic ion equals the charge of the ion.
The oxidation number of Hydrogen (H) is +1, but it is -1 in when combined with less electronegative elements.
The oxidation number of oxygen (O) in compounds is usually -2, but it is -1 in peroxides.
The oxidation number of a Group 1 element in a compound is +1.
The oxidation number of a Group 2 element in a compound is +2.
The oxidation number of a Group 17 element in a binary compound is -1.
The sum of the oxidation numbers of all of the atoms in a neutral compound is zero.
The sum of the oxidation numbers in a polyatomic ion is equal to the charge of the ion.
The given compound is,
Let the oxidation state of 'N' be, 'x'
Therefore, the oxidation number of nitrogen (N) is, (-3)
