Passage I A number of unsaturated hydrocarbons have the same molecular...
Explanation:
Geometrical isomerism occurs in unsaturated hydrocarbons that have a double bond between two carbon atoms. The double bond restricts the rotation around the carbon-carbon bond, and therefore, the atoms or groups attached to the double bond can be arranged in different ways, resulting in different isomers.
Given that all unsaturated hydrocarbons with molecular formula C11H22 give the same product on catalytic hydrogenation, it means they all have the same number and arrangement of carbon and hydrogen atoms. Therefore, the differences in the number and position of double bonds are responsible for the isomerism.
To determine the number of unsaturated hydrocarbons capable of exhibiting geometrical isomerism, we need to consider the possible arrangements of double bonds in a chain of 11 carbon atoms.
Possible double bond arrangements:
1. One double bond: This would result in a C=C bond between two adjacent carbon atoms, leaving nine carbon atoms to attach hydrogen atoms. There are no other possible isomers.
2. Two double bonds: This would result in a C=C bond between every other pair of carbon atoms, leaving seven carbon atoms to attach hydrogen atoms. There are two possible isomers: 3-methyl-1,5-octadiene and 2-methyl-1,6-octadiene.
3. Three double bonds: This would result in a C=C bond between every third pair of carbon atoms, leaving five carbon atoms to attach hydrogen atoms. There are three possible isomers: 3,5-dimethyl-1,4-octadiene, 2,6-dimethyl-1,5-octadiene, and 2,4-dimethyl-1,6-octadiene.
Therefore, there are five unsaturated hydrocarbons capable of exhibiting geometrical isomerism.
