Which type of hybridization are shown by carbon atoms present in but-I

1.	Which type of hybridization are shown by carbon atoms present in but-I-ene?
Answer» `sp^(2)` `sp^(3) and sp^(2)` `sp^(2) and sp` `sp^(3)` SOLUTION :`underset("but-1-ene")(underset(underset(underset(C )(sp^(3)))(uarr))(H_(3)C)-underset(underset(underset(C )(sp^(3)))(uarr))(CH_(2))-underset(underset(underset(C )(sp^(2)))(uarr))(CH)=underset(underset(underset(C )(sp^(2)))(uarr))(CH_(2)))`
