Assertion`:` `C_(6)H_(6)` does not decolourize `Br_(2)` water.
Reason`:` All the six carbon atoms have delocalized `pi-`electrons.

Which of the following does not decolourize Br_(2) water

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

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.

Assertion : C_(2)H_(2) molecule is linear. Reason : In C_(2)H_(2) carbon atoms remain unhybridized.
