How many carbon atoms are sp^(3) hybridized in but-2-en ?

1.	How many carbon atoms are sp^(3) hybridized in but-2-en ?
Answer» 4 2 3 1 Solution :`underset(sp^(3))underset(\|)overset(1)(CH_(3))-underset(sp^(2))underset(\|)overset(2)(CH)=underset(sp^(2))underset(\|)overset(3)(CH)-underset(sp^(3))underset(\|)overset(4)(CH_(3))` There is a double bond between `C_(2)` and `C_(3)`, they both POSSESS `sp^(2)` hybridization, there s a SINGLE bond between `C_(1)` and `C_(3)` so they both possess `sp^(3)` hybridization.
