CHBr = CHBr
CBr2= CH2
C.
CHBr = CHBr
Alkene shows geometrical isomerism due to restricted rotation of double bond. It is because the position of atoms or groups attached to the carbon atoms of the double bond gets fixed. If same group or atom is attached with double bond, then alkene does not show geometrical isomerism.
The IUPAC name of CH3-CH=CH-C≡CH is
pent-3-en-1-yne
