How many sigma and pi bonds , respectively , does ethanoic acid have? 8,0 7. 1 6. 1 5,1

## Step 1The molecule under consideration is ethanoic acid, also known as acetic acid, with the chemical formula . To determine the number of sigma ( ) and pi ( ) bonds in ethanoic acid, we need to analyze its molecular structure.## Step 2### **Carbon-hydrogen (C-H) and carbon-carbon (C-C) single bonds**Each of these is a sigma bond. In ethanoic acid, there are three C-H bonds in the methyl group ( ) and one C-C bond between the two carbon atoms.## Step 3### **Carbon-oxygen double bond (C=O)**This consists of one sigma bond and one pi bond. There is one C=O bond in the carboxylic acid group ( ).## Step 4### **Carbon-oxygen single bond (C-O)**This is a sigma bond. There is one such bond in the group.## Step 5### **Oxygen-hydrogen (O-H) single bond**This is a sigma bond. There is one O-H bond in the group.## Step 6Counting these bonds, we have:- Sigma bonds: 3 (C-H) + 1 (C-C) + 1 (C=O) + 1 (C-O) + 1 (O-H) = 7 sigma bonds.- Pi bonds: 1 (in the C=O bond).Thus, ethanoic acid has 7 sigma bonds and 1 pi bond.
