Question

Sum of oxidation numbers of carbon in acetaldehyde is options :-2,2,-4,-1

Answer 1

Answer:

allows you to calculate the average oxidation states as follows:

For C2H6O:000−4xFor C2H4O:000−2x=2x+6×(+1)+(−2)=2x+6−2=2x+4=2x=−2=2x+4×(+1)+(−2)=2x+4−2=2x+2=2x=−1

For CX2HX6O:0=2x+6×(+1)+(−2)0=2x+6−20=2x+4−4=2xx=−2For CX2HX4O:0=2x+4×(+1)+(−2)0=2x+4−20=2x+2−2=2xx=−1

Since these are averages, you can also arrive at the same conclusion by taking the arithmetic mean of all carbon atoms’ oxidation state; you will obviously arrive at the same result:
