Question

Which of the following has coordinate covalent bond ?

(A) H2O (B) CaCl2

(C) O3
(D)N2

std 11 chemistry give correct answer​

Answer 1

Answer:

option A is the answer.

Explanation:

A coordinate bond is a covalent bond (a shared pair of electrons) in which both electrons come from the same atom.

The nitrogen atom has a lone pair of electrons which are responsible for the formation of coordinate covalent bond in ammonium chloride

Hence, the correct option is A

Answer 2

The Coordinate covalent bond is present in the OZONE $(O_3)$ molecule. (OPTION C)

COORDINATE BOND -

• A type of covalent bond in which the electron is shared by a single atom.
• It is usually formed between two or more non-metals.
• The ozone molecules contain three oxygen atoms bonded together.
• The central oxygen forms a double covalent bond with one atom and a covalent coordinate bond with another oxygen atom.
• The bond provides stability to the donor and acceptor atoms.
• The bond is also present in carbon monoxide, the formation of ammonium, and hydronium ions.
• The diagram of the ozone molecule with the covalent bonds is given below -
