• pent-2-ene

What is the name of this isomer?

• 2-methylbut-2-ene

• 2-methylbut-1-ene

• 3-methylbut-1-ene

• pent-2-ene

Why is only pent-2-ene that has geometrical isomer (cis-trans isomerism)?

• The carbon atoms in the double bond are restricted in rotation

• They have different groups/atoms attached to carbon on the each side of doubly bonded carbon atom

• They have identical atoms on the same side of double bond

• The carbon atoms are attached to four different groups or atoms
