Current Question (ID: 21205)

Question:

$\text{The C--C bond length is maximum in:}$ $1.\ \text{C}_{60}$ $2.\ \text{Diamond}$ $3.\ \text{Graphite}$ $4.\ \text{C}_{70}$

Options:

1. $\text{C}_{60}$
2. $\text{Diamond}$
3. $\text{Graphite}$
4. $\text{C}_{70}$

Solution:

$\text{Hint: Diamond has the longest C--C bond length}$ $\text{The C--C bond length in diamond is 154 \text{ pm},}$ $\text{C--C bond length in graphite is 141.5 \text{ pm}.}$ $\text{The C--C bond length in C}_{60} \text{ is 143.5 \text{ pm}}$ $\text{and in C}_{70} \text{ it is 138.7 \text{ pm}.}$ $\text{Hence, option second is the correct answer}$
