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]
