Aryl halides: the halogen atom is bonded to the sp2 hybridised carbon atom of an aromatic ring. Like chlorobenzene, bromobenzene etc.
Alkyl halides: the halogen atom is bonded to an alkyl group. Like chloromethane, fluoro ethane etc.

Aryl means Aromatic benzene  ring Halides means hallogen. When we are looking at an aryl halide. its simply one of the four hallogen atoms bonds directly to the benzene ring  ..

   Alkyl halides also called haloalkanes or halogenoalkanes are chemical compounds that are often derived from alkanes that contain one or more halogens. We can also say that alkyl halides are a subset of the general class of halocarbons.Alkyl halide or haloalkanes are formed by the replacement of hydrogen atoms in an aliphatic hydrocarbon by halogen atoms (Fluorine, chlorine, bromine or iodine)

A lewis acif is therefore any substance, such as the H⁺ ion, that can accept a pair of nonbonding electrons. In other words, a lewis acid is an electron-pair acceptor.

Lewis acid is a chemical species that contains an empty orbital which is capable of accepting an electron pair from lewis base    

Lewis acid is a chemical species that contains an empty orbital which is capable of accepting an electron pair from lewis base.

In the Lewis theory of acid-base reactions, bases donate pairs of electrons and acids accept pairs of electrons. A Lewis acid is therefore any substance, such as the H+ ion, that can accept a pair of nonbonding electrons. In other words, a Lewis acid is an electron-pair acceptor.

Aromatic compound, any of a large class of unsaturated chemical compounds characterized by one or more planar rings of atoms joined by covalent bonds of two different kinds. The unique stability of these compounds is referred to as aromaticity.

#What is aromatic compound?

Ans:Aromatic compounds are chemical compounds that consist of conjugated planar ring systems accompanied by delocalized pi-electron clouds in place of individual alternating double and single bonds.

Examples:Benzene,Phenol,Toluene,Benzoic acid etc.

Aryl halide:

Aryl halide is an organic ccompound and aromatic compound in which one or more hydrogen atoms directly bonded to an aromatic ring is called aryl halide.

Aliphatic Compound :

Aliphatic compound is an chemical compound which the atoms are connected by single, double, or triple bonds to form nonaromatic structures is called Aliphatic compound.

Example: ethylene,propene and CH4

Assalamoalaikom, 

thank you for your question.

Question: What is heterogeneous?

Answer:  Heterogeneous means unlike, different in kind, incongruous. composed of parts of different kinds, having widely dissimilar elements or constituents.

Heterogeneous means different constituents or dissimilar components. 

A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture. 

The mixture of oil and water is a heterogeneous mixture.

Qs: Mention the types of bond in hydrocarbons?

= 1.Single Bond – single covalent bond in which they share 1 pair of electrons.

2.Double Bond – carbon atoms may share 2 pairs of electrons to form a double bond.

3.Triple Bond – carbon atoms may share 3 pairs of electrons to form a triple bond.

Aliphatic hydrocarbons are divided into three main groups according to the types of bonds they contain: alkanes, alkenes, and alkynes. Alkanes have only single bonds, alkenes contain a carbon-carbon double bond, and alkynes contain a carbon-carbon triple bond.
