Assertion : Alkenes having more than three carbon atoms exhibit chain

1.	Assertion : Alkenes having more than three carbon atoms exhibit chain isomerism. Reason : All carbon atoms in alkanes are sp-hybridized.
Answer» If both assertion and reason are correct and reason is correct explanation for assertion. If both assertion and reason are correct but reason is not correct explanation for assertion. If assertion is correct but reason is incorrect. If both assertion and reason are incorrect. Solution :Correct reason : A minimum of FOUR carbon ATOMS in necessary if a compound is to EXHIBIT chain ISOMERISM.
