Alkanes and alkynes do not exhibit geometrical isomerism. Explain. 

How will you explain that there exists two varieties of 1, 2,-dichloroethene while there is only one type of 1, 2-dichloroethane?

Draw cis and trans isomers of the following compounds. Also, write their IUPAC names:

(i) CHCl = CHCl

(ii) C₂H₅CCH₃ = CCH₃C₂H₅ 

Which of the following compounds will show cis-trans isomerism?

(i)(CH₃)₂C = CH-C₂H₅
(ii) CH₂ = CBr₂
(iii) C₂H₅CH = CH-CH₂
(iv) CH₃CH = CClCH₃ 

Draw the cis and trans structures of hex-2-ene. Which isomer will have higher b.p. and why?

Out of the two - trans-but-2-ene and cis-but-1-ene, which is more stable and why
