Question

The chemical reaction occurring between covalent molecules involves
1) breaking of existing bonds
2) formation of new bonds
3) evolution of heat energy
4) 1& 2​

Answer 1

Answer:

The answer is a option B

Answer 2

Answer:

Option 4) 1 & 2

Explanation:

• A chemical reaction refers to the transformation of participating chemical substances into new chemical substances.

• During the chemical reaction, two or more substances interact within themselves to form a product.

• A chemical reaction can take place between atoms, ions, or molecules and they form new bonds to form the product.

• Hence to form new bonds the previously existing bonds between reactants need to get broken so that the ions and molecules can interact and form the product.

Thus the chemical reaction between covalent molecules involves:

1)breaking of existing bonds and 2) formation of new bonds

Therefore option 4) 1 & 2 is correct.
