Explanation

Geometric isomerism is displayed by compounds having the same structural formula but different positions of atoms or groups on either side of a double bond.

It involves Geometric isomerism is displayed by compounds having the same structural formula but different positions of atoms or groups on either side of a double bond.

It involves cis-trans or E-Z isomers.

Explanation

I-Butene and II-Butene show position isomerism.

The double bond is located at different positions in the carbon chain, which distinguishes them.

Explanation

Ions and compounds are colorless is not a property of transition elements.

Transition elements often form colored compounds due to d-d electron transitions, while they also exhibit high melting points.

They are hard metals, and are good conductors of electricity.

Explanation

The electronic configuration of chromium (Proton number 24) is [Ar] 3d⁵ 4s¹.

Chromium exhibits an exception to the standard filling order to achieve a more stable half-filled d-subshell.

Explanation

Graphite is not an alloy; it is a pure form of carbon.

The bronze, steel, and brass are alloys made from a mixture of metals.

Explanation

The solubility of sulfates of alkaline metals generally decreases down the group.

As you move down the group, the lattice energy of the sulfates increases.

This making them less soluble in water.

Explanation

Aluminum oxide is not basic in nature; it is amphoteric, meaning it can act as both an acid and a base.

Unlike the other metal oxides listed, which are basic.

Explanation

The difference of lithium from the other alkali metals is mainly because of small radius and high charge density.

Lithium has a smaller atomic radius compared to other alkali metals.

This resulting in a higher charge density that leads to stronger ionic interactions and unique chemical properties.

Explanation

Sulfur (S) has the smallest atomic radius among the options.

Because atomic radius decreases across a period from left to right due to increasing nuclear charge, which pulls the electrons closer to the nucleus.

Francium (Fr) has the highest atomic radius in the periodic table.

Helium has the smallest atomic radius in the periodic table.

Explanation

Only lone pairs participate in determining geometry of molecules this statement is NOT a feature of Valence Shell Electron Pair Repulsion (VSEPR) theory.

As both lone pairs and bonding pairs of electrons participate in determining the geometry of molecules.

VSEPR theory states that electron pairs (both bonding and lone pairs) repel each other, influencing the shape of the molecule.
