Molecules in which the atoms are held together by __________ bonds have the strongest chemical linkages.

[A]. noncovalent
[B]. covalent
[C]. ionic
[D]. hydrogen

Answer: Option B

Explanation:

No answer description available for this question.

Covalent bonds are strongest chemical linkage, because all of the metal molecules in atom are linked by covalent bond.

Sejal said: (Apr 6, 2013)  
Covalent bond are strongest bond.

Avikash said: (Apr 30, 2013)  
Covalent bond is used in pharmectiual drugs.

Covalent bond are strongest bond Covalent bonds are the strongest of all bonds involving organic compounds. The hydrogen bonds help keep the tertiary structure together, but typically the more covalent (and hydrogen) bonds that a structure has, the harder it is to break up the molecule. Sulfide bonds are very strong, they are in DNA, RNA, amino acids, and plenty other compounds that make up the entire body. Cysteine and Methionine are the amino acids that have sulfide, and when they form those bonds, they amino acids (or protein eventually) usually has a structural role, but not always.

Covalent bond are strongest bond in chemistry formed by sharing of electrons and require more energy to break them. This fact explains why primary structure of biomolecules like DNA, RNA and Proteins have covalent bond in their structure. The rest of option are nothing but non covalent bond and can be easily broken down by low energy. This explains why the binding between the substrate and enzyme occurs by non covalent interaction. This makes the enzyme reusable.

I think ionic bond is strongest that's why ionic compounds have extraordinary high M.P and B.P like NACL.

The easy way to determine that is to measure the energy it takes to break the bond. That quantity is called bond dissociation energy. The greater the energy it takes to break the bond, the stronger that bond must be. It turns out that most ionic bonds are considerably more difficult to break than covalent bonds. I think!

Alok Sahu said: (Jun 28, 2016)  
The ionic bonds are stronger than that of covalent bonds. Because its dissociation energy is more than covalent bond.

J.Christian said: (Jun 28, 2016)  
Covalent bonds are the strongest bonds whereas non-covalent are the weakest which is easier for the enzymes to break the bond.

Edith said: (Sep 27, 2016)  
Covalent bonds are very strong and they are present in non-metals. Molecules in an atom are linked by covalent bonds.

Rajan said: (Dec 1, 2017)  
It Should be Ionic bond because ionic bond have higher energy of dissociation

V. Dhanalakshmi said: (Feb 8, 2019)  
Covalent bonds is the answer. I agree.

Israel said: (Jan 21, 2020)  
It is electrovalent or ionic bonding not covalent bonding because ionic bonding are stronger than the covalent bonding.

Kundan said: (May 14, 2020)  
Covalent bond is the strongest bond in the chemical bonding between atoms.
