1.	Which of the following compounds contain all the carbon atoms in the same hybridisation state ?
Answer» `H-C -= C-C-=C-H` `CH_(3)-C-=C-CH_(3)` `CH_(2)=C=CH_(2)` `CH_(2)=CH-CH=CH_(2)` Solution :(a) `H - OVERSET(sp)(C) -=overset(sp)(C)-overset(sp)(C)-=overset(sp)(C)-H`(B) `overset(sp^(3))(C)H_(3)-overset(sp)(C)-=overset(sp)(C)-overset(sp^(3))(C)H_(3)` (c) `overset(sp^(2))(C)H_(2)=overset(sp)(C)=overset(sp^(2))(C)H_(2)`(d) `overset(sp^(2))(C)H_(2) =overset(sp^(2))(C)H-overset(sp^(2))(C)H = overset(sp^(2))(C)H_(2)`
