Which condensed structural formula represents an unsaturated compound?
(1) CH3CHCHCH3
(2) CH3CH2CH3
(3) CH3CH3
(4) CH4



Sagot :

Number(1).A carbon atom makes 4 bondings.As the second Carbon in the conpuond has only one hidrogen,it has to make other 3,two with the other carbon atoms,one of them Being a double,making the compound unsaturated.PS:Sorry for my english,um fron Brazil

Answer: The correct answer is option (1).

Explanation:

The general formula of alkanes (Saturated compounds) is given as:[tex]C_nH_{2n+2}[/tex]

The general formula of alkene  (Unsaturated compounds)is given as:[tex]C_nH_{2n}[/tex]

The general formula of alkynes (Unsaturated compounds)is given as:[tex]C_nH_{2n-2}[/tex]

1. [tex]CH_3CHCHCH_3:C_4H_8[/tex] unsaturated hydrocarbon

2. [tex]CH_3CH_2CH_3:C_3H_8[/tex] Saturated hydrocarbon

3.[tex]CH_3CH_3:C_2H_6[/tex] Saturate hydrocarbon

4. [tex]CH_4[/tex] Saturated hydrocarbon
