Answer 2

GiveN :-

• The Compounds $\sf{ C_2H_4 , C_3H_6 , C_4H_8 }$

To FinD :-

• The general name and the general fórmula of the carbon compounds .

SolutioN :-

A homologous series is given to us and we need to find the general fórmula and general name of the Carbon Compounds. So the given series is ,

$\sf :\implies \gray{ C_2H_4 , C_3H_6 , C_4H_8}$

The first member of this séries is $\sf C_2H_2$ . The number of carbon and Hydrogen Atoms is 2.

Here each succesive members differ by $\sf -CH_2$ group and a molecular weight of 14g.

This homologous series is of Alkénes , which has a general formula of $\sf C_nH_{2n}$

The name of the Compounds in the series is as follows :-

$\textsf{: \implies \pink{ Ethene } , \gray{ Propene } , \pink{ Bútene } , \gray{ Pentene} }$

•General Fórmula - $\sf \underline{ C_n H_{2n}}$

• General Name - $\sf \underline{ Alkénes }$
