Question

the bond dissociation energy to break 4 c - c bond(s) in 1 mole of hexane ch₃ch₂ch₂ch₂ch₂ch₃ molecules is

Explanation:

Step1: Determine the bond energy of C - C bond

From the table, the bond energy of \(C - C\) single bond is \(346\ \text{kJ/mol}\).

Step2: Calculate the energy to break 4 \(C - C\) bonds

Since we need to break 4 \(C - C\) bonds and the energy per \(C - C\) bond is \(346\ \text{kJ/mol}\), we use the formula \(E = 4\times\) (bond energy of \(C - C\) bond).

$$E=4\times346\ \text{kJ/mol}$$

$$E = 1384\ \text{kJ}$$

Answer:

\(1384\)
