Answer 1

Answer:

All halogen compounds are less inflammable than hydrocarbon the inflammability decreases with increase in halogen content.

Answer 2

Explanation:

$\huge{ \underline{ \pink{ \: answer : }}}$

All halogen compounds are less inflammable than hydrocarbon the inflammability decreases with increase in halogen content.

PHYSICAL STATE - DEFINITION→

Halo alkanes are commonly colourless, odourless, and hydrophobic. There are relatively heavier than the alkanes. Haloarenes are normally colourless or crystalline solid. Haloarenes are heavier than the water.

MELTING POINT - DEFINITION→

Melting point of a compound depends upon the strength of lattice structure of a compound. Melting point also follows the same trend as boiling point. An exception to this is para-isomers. The para-isomers have higher melting as compared to their ortho and meta-isomers. It is due to symmetry of para-isomers that fits in crystal lattice better as compared to ortho and meta-isomers.

MELTING POINT AND BOILING POINT OF HALOARENES - DEFINITION→

Boiling point and melting point of haloarenes are near about same as of alkyl halides, which containing same number of carbon atoms.

Monohalogen derivative of benzene have boiling point in a proper order i.e. iodo>bromo>chloro>fluro.

The melting point and boiling point of halogens atoms increases with an increase in the size of the aryl group.

______________________________________

DENSITY OF HALOALKANES - DEFINITION→

Density is directly proportional to the mass of compound, hence down the homologous series, density increases, also fluoro derivatives are lesser dense than chloro derivatives; chloro derivatives are less dense than bromo derivatives and so on.

______________________________________

DIPOLE MOMENT OF HALOALKANES AND HALOARENES - DEFINITION→

Dipole moment depends on the difference in electronegativity of carbon and halogens and as we know that the electronegativity of halogens decreases down the group, the dipole moment also decreases. There is an exception of C-Cl and C-F dipole moments. Though the electronegativity of Cl is less than F, but the dipole moment of C-Cl bond is more than C-F.

INFLAMMABILITY OF HALOALKANES AND HALOARENES - DEFINITION→

All halogen compounds are less inflammable than hydrocarbon the inflammability decreases with increase in halogen content.
