Question

The bond dissociation energy to break 3 C-H bond(s) in 1 mole of ethanol (CH₃CH₂OH) molecules is...

a) 1.5 kJ/mol
b) 3.0 kJ/mol
c) 4.5 kJ/mol
d) 6.0 kJ/mol

Answer 1

The bond dissociation energy to break 3 C-H bonds in 1 mole of ethanol is not provided in the given options.

Step-by-step explanation:

The bond dissociation energy to break 3 C-H bond(s) in 1 mole of ethanol (CH₃CH₂OH) molecules can be calculated by finding the average bond energy of the C-H bonds in ethanol. Each C-H bond requires 439 kJ/mol to break, and there are four C-H bonds in ethanol. So, the total bond dissociation energy for 3 C-H bonds in ethanol would be:

3 * 439 kJ/mol = 1317 kJ/mol

Therefore, the correct answer is not listed among the given options.
