In cyclobutane, there is angle strain as bond angle (C-C-C) is close to 90°. Due to this kind of angle effecting overlapping of orbitals cannot take place.

In cyclobutane, there is angle strain as bond angle $(C - C - C)$ is close to $9 0^{\circ}$ . Due to this kind of angle effecting overlapping of orbitals cannot take place.
