Geometrical isomerism is shown by compounds having at least one C = C and the two groups attached to each carbon must be different.
So, 1,1-dichloro-1-pentene does not show geometrical isomerism due to the presence of two similar
Cl atoms on the same C-atom.

Which of the following does not show geometrical isomerism?a)1,2- dich...
Explanation:
Geometrical Isomerism:
Geometrical isomerism is a type of stereoisomerism where different spatial arrangements of atoms are possible due to restricted rotation around a double bond or ring.
Given Compounds:
a) 1,2-dichloro-1-pentene
b) 1,3-dichloro-2-pentene
c) 1,1-dichloro-1-pentene
d) 1,4-dichloro-2-pentene
Analysis:
- Option a) 1,2-dichloro-1-pentene shows geometrical isomerism because the two chlorine atoms are on the same carbon atom and restrict rotation around the double bond.
- Option b) 1,3-dichloro-2-pentene shows geometrical isomerism because the two chlorine atoms are on adjacent carbon atoms, leading to different spatial arrangements.
- Option c) 1,1-dichloro-1-pentene does not show geometrical isomerism because both chlorine atoms are attached to the same carbon atom, allowing free rotation around the carbon-carbon single bond.
- Option d) 1,4-dichloro-2-pentene shows geometrical isomerism as the two chlorine atoms are on non-adjacent carbon atoms, leading to different spatial arrangements.
Therefore, option c) 1,1-dichloro-1-pentene does not exhibit geometrical isomerism.
