Question

what was the defect in dobereiner's triad​

Answer 1

Answer:

Dobereiner could identify only three triads. He was not able to prepare triads of all the known elements. All the known elements could not be arranged in the form of triads. For very low mass or for very high mass elements, the law was not holding good.

Explanation:

Limitations of Dobereiner's Triads are as follows:

• All known elements could not be classified into groups of triads on the basis of their properties.

• Not all groups obeyed the Law of Triads, For example, Nitrogen family/group did not obey the Law of Triads.
