Question

11. Which has weakest bond
(a) Diamond
(b) Neon (Solid)
(c) KCL
(d) Ice

​

Answer 1

Answer:

Ice has the weakest bond.

Explanation:

• Diamond is the hardest substance on Earth due to the presence of covalent bonding. There are four electrons in the carbon atom's outermost shell. In order to create exceptionally powerful covalent bonds in diamond, these electrons are shared with four additional carbon atoms, resulting in a tetrahedral crystal that is incredibly rigid. Diamond is among the world's hardest materials because of this straightforward, tightly-bonded structure.
• Similarly, because of the covalent bonds inside it, neon is a highly stable inert gas.
• In the case of KCl, the ionic bond is formed as a result of the electronegavity difference between the potassium and chloride atoms.
• Each H₂O molecule's two hydrogen atoms form a hydrogen bond with an adjacent H₂O molecule to form an ice crystal. Therefore, in ice, weak hydrogens bonds are present.
• Since hydrogen bonds are weaker than ionic and covalent bonds, ice has the weakest type of bonding.

Answer 2

Answer:

weakest bond-(b) Neon (Solid)

Explanation:

Correct answer: (b) Neon (Solid)

A molecule is made up of two or more atoms connected by covalent connections. Given that neon is an atom, it is not a part of a molecule.

Incorrect answer:(a)Diamond

Each carbon atom in diamond is connected to four other carbon atoms by covalent bonds, forming a massive covalent structure.

The carbon atoms require a typical lattice configuration.

(c) KCL

Chemical bonding is the process used to join components to create compounds. KCL is an illustration of ionic bonding.

(d) Ice

The crystalline lattice of ice is dominated by a regular chain of hydrogen bonds, which places the water molecules further apart than they do in liquid water.

This explains why water loses density as it freezes.

Which has the weakest bond, finally? (b) Neon (solid)
