1.	Assertion (A): All the carbon atoms in H_(2)C = C = CH_(2) are sp^(2) hybridised. Reason (R) : In this molecule all the carbon atoms are attached to each other by double bonds.
Answer» Both A and R are correct and R is the correct EXPLANATION of A. Both A and R are correct but R is not the correct explanation of A. Both A and R are not correct. A is not correct but R is correct. Solution :Correct (A). In `CH_(2) = C = CH`, the central carbon is sp-hybridizedwhile the TERMINAL carbon atoms are `sp^(2)`-hybridized.
