Which of the following wil have least hindered rotation about carbon carbon bond?
Which of the following wil have least hindered rotation about carbon carbon bond?
Ethane
Ethene
Ethyne
Hexachoroethane
Solution
Free rotation around carbon-carbon bond takes place easily in alkanes. Now ethane and hexachloroethane both are alkanes, but in hexachloroethane bulky chlorine atom is present while ethane is least hindered.
