The correct answer is #option (4)#

The percentage of each element in the compound is

#{(%C=24/80*100=30%),(%H=4/80*100=5%),(%O=32/80*100=40%):}#

#C=12#

#H=1#

#O=16#

Calculate the number of moles

#{(C=30/12=2.5),(H=5/1=5),(O=40/16=2.5):}#

Dividing by #2.5#

#{(C=2.52.5=1),(H=5/2.5=2),(O=2.5/2.5=1):}#

The empirical formula is #CH_2O#

The correct answer is #option (4)#
