Meso compounds have a plane of symmetry. In case of butan-2, 3-diol, gauche form is the most stable due to intramolecular H-bonding.
The correct answer is option (B):
A cubic solid is made up of two elements $X$ and $Y$ Atoms of $X$ are present on every alternate corner and one at the enter of cube $Y$ is at $\frac{1}{3} td$ of the total faces The empirical formula of the compound is
List-I | List-II | ||
(A) | Hexagonal | (I) | ∝ ≠ β ≠ γ ≠ 90° |
(B) | Orthorhombic | (II) | ∝ = γ = 90°, β ≠ 90° |
(C) | Triclinic | (III) | ∝ = β = 90°, γ = 120° |
(D) | Monoclinic | (IV) | ∝ = β = γ = 90° |
Solids are substances that are featured by a definite shape, volume, and high density. In the solid-state, the composed particles are arranged in several manners. Solid-state, in simple terms, means "no moving parts." Thus solid-state electronic devices are the ones inclusive of solid components that don’t change their position. Solid is a state of matter where the composed particles are arranged close to each other. The composed particles can be either atoms, molecules, or ions.
Based on the nature of the order that is present in the arrangement of their constituent particles solids can be divided into two types;
