Calculate the tota bond energy of ethanol from this info:(C_C=347,C_H=414,H_O=464,C_O=360)kJmol-1.Thanks for responding
from what?
The information provided in the bracket above.
To calculate the total bond energy of ethanol, we need to consider the bonds present in the molecule and their respective bond energies. Ethanol (C₂H₅OH) consists of carbon (C), hydrogen (H), and oxygen (O) atoms bonded together.
Given this information:
- C-C bond energy = 347 kJ/mol
- C-H bond energy = 414 kJ/mol
- H-O bond energy = 464 kJ/mol
- C-O bond energy = 360 kJ/mol
We can determine the total bond energy by calculating the sum of the bond energies for each bond in the molecule.
First, let's determine the number of each type of bond in ethanol:
- There is one C-C bond.
- There are six C-H bonds.
- There is one H-O bond.
- There is one C-O bond.
Now, we calculate the total bond energy:
Total bond energy = (Number of bonds) x (Bond energy for each type of bond)
Total bond energy = (1 C-C bond) x (347 kJ/mol)
+ (6 C-H bonds) x (414 kJ/mol)
+ (1 H-O bond) x (464 kJ/mol)
+ (1 C-O bond) x (360 kJ/mol)
Total bond energy = (347 kJ/mol) + (6 x 414 kJ/mol) + (464 kJ/mol) + (360 kJ/mol)
Calculating this expression gives us the total bond energy of ethanol.
