If the z-axis is the molecular axis, then `piMOs` are formed by the overlap of
(i) `p_z` and `p_z` (ii) `p_y` and `p_y`
(iii) `s` and `p_z` (iv) `p_x` and `p_x`

If z-axis is the molecular axis, then the p-mole-cular orbitals are formed by the overlap of :

Considering x-axis as molecular axis, which out of the following will form a sigma bond. (i) 1s and 2p_(y) (ii) 2p_(x)and 2p_(x) (iii) 2p_(x)and 2p_(z) (iv) 1s and 2p_(z)

If z - axis is the internuclear axis, which of the following combinations are not allowed ? (i) 2s and 2s (ii) 1s and 2p_(x) (iii) 2pP_(y) and 2p_(y) (iv) 2p_(x) and 2p_(z) (v) 2p_(z) and 2p_(z) (vi) 2s and 2p_(z) (vii) 2p_(x) and 2p_(y) .

Considering z - axis as the internuclear axis, which of the following will not form sigma bond? (a) 2s and 2s (b) 2p_(y) and 2p_(y) (c ) 2s and 2p_(z) (d) 2p_(x) and 2p_(z) (e) 2p_(z) and 2p_(z) .

If the point P lies on Z - axis , then coordinates of p are of the form ……….
