Question

What are homologus series? How covalent compounds different from ionic
compounds with respect to
i) Physical state
ii) Solubility
​

Answer 1

such a series of compounds in which the same functional group substitutes for hydrogen in a carbon chain is called a homologous series

Explanation:

1) Ionic compounds are formed from strong electrostatic interactions between ions, which result in higher melting points and electrical conductivity compared to covalent compounds. Covalent compounds have bonds where electrons are shared between atoms.

2)Ionic compounds are non-volatile and have high melting and boiling points. They are usually soluble in water but insoluble in organic solvents. ... Covalent compounds are volatile and have low melting and boiling points. They are usually insoluble in water but soluble in organic solvents.
