Assertion : In CH_(2)=C=CH_(2), all the carbon atoms are sp^(2)-hybridized. Reason : All the hydrogen atoms lie in one plane.

Assertion : In CH_(2)=C=CH_(2), all the carbon atoms are sp^(2)-hybrid

1.	Assertion : In CH_(2)=C=CH_(2), all the carbon atoms are sp^(2)-hybridized. Reason : All the hydrogen atoms lie in one plane.
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 assertion : `underset((sp^(2)))(CH_(2))=underset((sp))(C)=underset((sp^(2)))(CH_(2))` Correct reason : The hybridisation state of carbon atom is RELATED to the nature of and number of hydrogen atoms ATTACHED to it.
