How can cyclobutane (60°), cyclopentane (108°), and cyclohexane (120°) all be sp3 hybridized? NEED ASAP PLEASE
Select one:

a.
They aren’t. Bond angles that cause ring strain on the molecule do not allow for all cycloalkanes to be sp3 hybridized.

b.
They’re still alkanes. Cycloalkane carbons are sp3 hybridized to create opportunities for four single bonds which all alkanes have.

c.
Cyclobutane and cyclopentane are sp3 hybridized, but cyclohexane is above the 109.5° bond angle limit. Since it must switch between boat and chair conformations, it cannot be sp3 hybridized.

d.
They can’t. Alkanes are sp hybridized, not sp3 hybridized.
