yKpoI14uk [10]

<h3>Answer:</h3>

A coordinate bond

<h3>Explanation:</h3>

A chemical bond is a force of attraction between two or more atoms of elements.
Covalent bond is a type of chemical bond that occurs between non-metal atoms.
It occurs as a result of sharing of electrons between the non-metal atoms.
Atoms involved in covalent bond formation may contribute equally to the bond formation or the electrons shared may come form one of the atoms.
When the electrons shared in a covalent bond are derived from one atom, then the covalent bond is known as a coordinate bond.

An ordered list of chemical substances is shown.

Answer : The correct option is, (C) 2, 4 and 5.

Explanation :

Combustion reaction : It is a type of reaction in which a hydrocarbon react with an oxygen molecule to give carbon dioxide, water as a product.

For example : Methane react with oxygen to give carbon dioxide and water.

$CH_4+2O_2\rightarrow CO_2+2H_2O$

In the given list of chemical substances, $CuO,Cu_2O,Li_2O$ are in oxide form. They can not be both reactant and product of a single combustion reaction.

In the given list, $C_2H_5NH_2$ is the only hydrocarbon which shows a combustion reaction. That means $C_2H_5NH_2$ react with $O_2$ to give $CO_2,H_2O$ and $N_2$ as a product.
