Question

Two carbon compounds X and Y have the molecular formula C4H8 and C5H12 respectively. Which one of these is most likely to show addition reaction? Justify your answer. Also give the chemical equation to explain the process of addition reaction in this case.

Answer 1

C4H8 will go addition reaction due to the presence of electrons in the double bond.
Reaction with Bromine
C4H8+Br2 will give C4H8Br2 (1,2-dibromo butane

Answer 2

Explanation:

Carbon compounds X the molecular formula $C_4H_8$

Molecular formula corresponds to the general formula of alkene .

$C_nH_{2n}:C_4H_8:C_4H__{2\times 4}$

Alkene are unsaturated hydrocarbons with double bond present between carbon carbon atom. These hydrocarbons undergo addition reaction.

$C_4H_8+H_2\rightarrow C_4H_{10}$

Carbon compound Y the molecular formula $C_5H_{12}$

Molecular formula corresponds to the general formula of alkane .

$C_nH_{2n+2}:C_5H_{10}:C_5H__{2\times 5+2}$

Alkane are saturated hydrocarbons with single bond present between carbon carbon atom. These hydrocarbons does not undergo addition reaction.
