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.

Assertion (A) . All the carbon atom 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

Assertion (A) . All the carbon atom 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

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

All carbon atoms sp^(2) hybridised in

Note: In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices. Assertion : In allene (C_3 H_4) all carbon atoms are sp^2 hybridised. Reason : All the three carbon atoms are joined by double bond.

Statement-1: All the hydrogen atoms in CH_(2)=C=CH_(2) lie in one plane. Statement-2: All the carbon atoms in it are not sp^(2) hybridized .

Statement-1: All the hydrogen atoms in CH_(2)=C=CH_(2) lie in one plane. Statement-2: All the carbon atoms in it are not sp^(2) hybridized .
