Geometrical Isomerism: When Structure Changes Everything

What is the primary difference between two isomers that exhibit geometrical isomerism?

• The presence of a triple bond

• The number of carbon atoms

• The spatial arrangement of groups around a double bond

• The type of chemical bonds present

In the case of 2-butene, what distinguishes the CIS isomer from the trans isomer?

• The trans isomer has no methyl groups.

• The CIS isomer has methyl groups on the same side of the double bond.

• The CIS isomer has methyl groups on opposite sides of the double bond.

• The trans isomer has methyl groups on the same side of the double bond.

Which type of isomerism is exhibited by 2-butene?

• Conformational isomerism

• Structural isomerism

• Geometrical isomerism

• Optical isomerism

Why is the trans isomer of cyclohexene generally not stable?

• It is too small in size.

• It has a strained arrangement.

• It has too many hydrogen atoms.

• It lacks a double bond.

In higher cycloalkenes like cyclodekene, why does the trans isomer exist?

• It is less strained due to a larger ring size.

• It has no double bonds.

• It forms a triple bond.

• It has fewer carbon atoms.
