Which one of the following complexes can exhibit geometrical isomerism? which one of the following complexes can exhibit geometrical isomerism? [cu(nh3)4]2+ (square planar) [zn(nh3)2cl2] (tetrahedral) [cu(nh3)5cl]2+ (octahedral) [pt(nh3)2cl2] (square planar) all of the above can exhibit geometrical isomerism.

shows geometrical isomerism.

Explanation:

Geometrical isomerism:

"Molecules having same molecular formula but the but difference in the arrangement of atoms."

Cis and trans isomers are called geometrical isomers.

Among the given , shows geometrical isomerism.

The cis and trans forms of the are as follows.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
