Problem

According to VBT, a covalent bond forms by overlap of half-filled atomic orbitals containing electrons with opposite spins. According to the type of overlap, covalent bonds can be classified as (a)

\sigma

-bond, (b)

\pi

-bond, and (c)

\delta

-bond. The combination of orbitals that cannot produce a non-bonding molecular orbital is, with the internuclear axis as the

z

-axis: (1)

p_y+d_{x^2-y^2}

(2)

p_z+d_{yz}

(3)

s+d_{xz}

(4)

d_{xy}+d_{xy}
