Which of the following elements does not show allotropy?
विकल्प
Nitrogen
Bismuth
Antimony
Arsenic
उत्तर
Nitrogen
Explanation:
Nitrogen does not show allotropy due to its weak N – N single bond.
Therefore, ability of nitrogen to form polymeric structure or more than one structure become less. Hence, nitrogen does not show allotropy.
