How many sigma bonds are in a molecule of diethyl ether, C2H5OC2H5? — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Write down the expanded structural formula of diethyl ether: CH3-CH2-O-CH2-CH3. Step 2: Count all the single covalent bonds, which represent the sigma bonds in the molecule. Step 3: There are 10 C-H bonds, 2 C-C bonds, and 2 C-O bonds, giving a total of 10 + 2 + 2 = 14 sigma bonds, which matches option (a).
