Question

The numbers of lone pairs and bond pairs in hydrazine are, respectively.

• A. $2$ and $4$
• B. $2$ and $6$
• C. $2$ and $5$
• D. $1$ and $5$

Answer 1

Answer: (C)

$2$ and $5$

Based on the structure it is clear that the number of lone pairs and bond pairs in hydrazine are 2 and 5 (one lone pair on each nitrogen) and five bond pairs include one bond pair between two nitrogen atoms and four bond pairs between nitrogen and hydrogen atoms.

Hence option C is correct.
