Which of the following types of bonding does not involve the formation of new substances?

A. Metallic

B. Covalent

C. Co-ordinate

D. Electrovalent

QUICK ANSWER…

A

DETAILS…

Metallic bonding is a type of chemical bonding where atoms of a particular metal are held together by mutual sharing of free electrons in a positively charged strong lattice. Metallic bonds do not necessarily result in the formation of new substances.

Now for the right answer to the above question:

1. Option A is correct. metallic bonding only serves to give metals their definite lattice structure, they do not necessarily result in the formation of new compounds.
2. Option B is incorrect. covalent bonds mostly result in formation of new substances.
3. C is incorrect. co-ordinate bonds are a type of covalent bond which could result in the formation of new substances.
4. D is not the correct answer. electrovalent bonds compulsorily result in formation of new substances.

KEY-POINTS…

You may please note these/this:

• Metallic bonds result in the formation of strong and stable pure metals and not necessarily new substances.
