Define homologous series. Differentiate between alkane and alkene
Answers
Answer:
Homologous Series;
Homologous Series. Homologous Series. A series of carbon compounds in which same functional group substitutes the hydrogen atom is called a homologous series. These compounds have similar chemical properties due to the addition of same kind of functional group throughout the chain.
Explanation:
Alkane;
The main differences between alkanes and alkene are their functional groups and degree of unsaturation. Alkanes are known as saturated hydrocarbons
C-C ,,it's consist of Singal bond between two,molecules or atoms.
Alkene;
. Alkenes are known unsaturated hydrocarbons as it contains a C=C bond in its structure. The C=C is its functional group.

The difference between alkanes and alkene are as follows:
Alkane
Alkene
1. It is a hydrocarbon in which the atoms are connected to each other through a single covalent bond.
It is a hydrocarbon in which the atoms are connected to each other through a double bond.
2. The general formula of alkanes is: CnH2n+2
The general formula of alkenes is: CH2n
3. They burn in air with blue and non-sooty flame.
They burn in air with a yellow and sooty flame.
4. Alkanes undergoes substitution reactions. More over Alkanes are not able to decolorize the red-brown color of Bromine (Br2) water.
They undergo addition reactions and not substitution reactions and can decolorize the Red-Brown color of Br2 water.
One of the member of alkane is: Methane having molecular formula (CH4). The structure of CH4 is as follows:
One of the member of alkene is Ethene having molecular formula C2H4 and the structure of Ethene is as follows:
(b) Alkanes generally burns with a clear flame. They burn in air with a blue and non-sooty flame as the carbon percentage in the alkane is low and it gets oxidized completely in air
