If a homonuclear diatomic molecule is oriented along the Z-axis, the molecular orbital formed by linear combination of $\mathrm{p}_{\mathrm{x}}$ orbitals of the two atoms is
(a)$\sigma$
(b)$\sigma^{*}$
(c)$\pi$
(d)$\delta$
Answer
Answer: C ✓ checked by 4AB · confidence high
Explanation
With the bond along z, the two p_x orbitals overlap side-on, giving π (and π*) MOs (c).
