Which of the following molecules represents the order of hybridisation

1.	Which of the following molecules represents the order of hybridisation sp^(2), sp^(2), sp, sp from left to right atoms?
Answer» `CH_(3)- CH= CH-CH_(3)` `HC -= C- C -=CH` `CH_(2)= CH-CH= CH_(2)` `CH_(2)= CH-C -=CH` Solution :`UNDERSET(sp^(2))(CH_(2))= underset(sp^(2))(CH)- underset(sp)(C )-= underset(sp)(C H)`
