Chemical Bonding and Molecular Structure

This option is correct because in Tert-butyllithium, (CH₃)₃C, Li⁺ Lithium metal is directly bonded to carbon atom, hence Tert-butyllithium is an organometallic compound.

The name atom comes from the Greek word (atomos, indivisible) which means indivisible, something that cannot be divided further. 

It is a member of group IV A. 

A binary compound consists of exactly two different elements. HCl (hydrochloric acid) is composed of hydrogen and chlorine, making it a binary compound.

Co-ordination compounds are compounds in which the central metal atom is linked to a number of ions or neutral molecules by co-ordinate bonds.

Important complex in which a metal is bound to only one kind of donor group are known as homoleptic complexe e.g., [CO (NH₃)₆)]³⁺ .In this componud the donor group is only NH_3.

Alfred Werner suggested in 1893 that metal ions exhibit what he called primary and secondary valences. This first theory was called the Werner's theory of co-ordination compounds.

All the above mentioned three factors affect  the stability of the complex ion.

Bonding in a complex ion is due to electrostatic interactions between the positively charged nucleus of the central metal ion and electrons in the ligands i.e., attractive as well as repulsive interactions

Compounds, which give different ions in solution although they have same composition are called ionization isomers. There is an exchange in groups between the coordination sphere of the metal ion and ions outside the sphere.

The ionic crystals consist of positively and negatively charged ions arranged in a regular fashion throughout the crystal. They form a network of positive and negative ions in three dimension in such a way that cations and anions occupy alternate sites. These are held together by strong electrostatic forces.Common examples of ionic crystals are, salts like NaCl, KNO₃, LiF etc. 

Aluminium iodide is any chemical compound containing only aluminium and iodine. Aluminium iodide is employed as a catalyst to break certain kinds of C-O and N-O bonds. It cleaves aryl ethers and deoxygenates epoxides.

Aluminium nitride (AlN) is a nitride of aluminium. Its wurtzite phase (w-AlN) is a wide band gap (6.2 eV) semiconductor material, giving it potential application for deep ultraviolet optoelectronics.
