Question

Give reasons:
A.Haloalkanes easily dissolve in organic solvents
B.Iodoform is used as an antiseptic
C.Haloalkanes are more reactive than haloarenes towards nucleophilic substitution reactions.

Answer 1

We must know that the iodine is an antibacterial agent. Haloarenes shows partial double bond at $C - X$ bond.

Complete step by step answer:
Let’s start with answering the questions.
A.In this statement we are asked to give reason regarding the haloalkanes easily dissolving in organic solvent. The reason behind this is that the intermolecular forces between the haloalkanes and organic solvent are the same as the ones being broken in the separate haloalkanes and solvent molecules.

B.In this statement we are asked the reason behind the Iodoform as an antiseptic. Iodine is widely used as an antiseptic and the reason behind this is Iodine which is released from the Iodoform acts as an antibacterial agent which results in antiseptic properties of Iodoform.

C.In this statement we are asked the reason behind the more reactive nature of haloalkanes as compared to haloarenes in nucleophilic substitution reactions. The reason behind this is that in the case of haloarenes the $C - X$ bond gets a partial double bond which leads to stronger bonding between the two and hence substitution become difficult, whereas in case of haloalkanes it is impossible to get a double bond characteristic in $C - X$ bond and hence it is more reactive than haloarenes towards nucleophilic substitution reaction.

Note:
Haloalkanes are widely known and we can use it in many industries. It has many industrial applications and is known by common or commercial names. Many of its uses include its use as refrigerants, flame retarders, flame extinguisher, propellant, and solvents and in pharmaceuticals.
