Question

Which of the following will give addition reaction and why ? C4H10 ;C2H6 ;CH4 ; C3H8

Answer 1

None of the above give addition reaction.

Explanation:

• Addition reaction is the change of the pie bond by the addition of some of the halogen or other compounds to the alkane.  

• Now this is possible only when there is saturation in the compound. Saturation is present in alkene and alkynes. All of the given compound are alkanes.  

• Alkanes have no saturation present. Hence the addition reaction is not possible for these compounds.

• Alkanes have the molecular formula of CnH2n+2. Hence all of the compounds are alkane.

Answer 2

None of them

Explanation:

Unsaturated hydrocarbons will give addition reactions. A chemical reaction in which one molecule combines with another to form a larger molecule with no other products is called an addition reaction. Example: C2H4 and C3H4 are unsaturated hydrocarbons. So these molecules will give addition reactions.

From the given list of C4H10 ;C2H6 ;CH4 ; C3H8, none of them are unsaturated hydrocarbons. So none of them will have addition reactions.
