C2H4O oxidation number is -1
2x+1(4)+1(-2)=0
2x+4-2=0
2x+2=0
2x=-2
x=-2/2
x=-1
The oxidation number of carbon in C2H4O is +2, as each hydrogen has an oxidation number of +1 and each oxygen has an oxidation number of -2. By setting up the equation 2x + 4(+1) + 1(-2) = 0, you can solve for x to find the oxidation number of carbon.

What is the oxidation numberS of ethanal?
The oxidation state of carbon in ethanal (C2H4O) is +2, as it is bonded to two more electronegative oxygens. The oxidation state of oxygen is -2, while the hydrogen atoms have an oxidation state of +1.
Which one of the following formulas represents an aldehyde a c6h10o5 b c2h4o c c2h5oh?
The formula that represents an aldehyde is c) C2H4O. Aldehydes have the general formula RCHO, where R is an alkyl or aryl group.
What is the oxidation number of acetate?
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
What is the oxidation number of H2CO2?
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
What is the oxidation number of nitrosyl?
The oxidation number of nitrosyl (NO) is +1. Nitrogen typically has an oxidation number of -3, and oxygen typically has an oxidation number of -2. In NO, nitrogen has a -3 oxidation number and oxygen has a -2 oxidation number, leading to an overall oxidation number of +1 for the nitrosyl ion.
What is the oxidation numberS of ethanal?
The oxidation state of carbon in ethanal (C2H4O) is +2, as it is bonded to two more electronegative oxygens. The oxidation state of oxygen is -2, while the hydrogen atoms have an oxidation state of +1.
What is the chemical formula of PVA?
The chemical formula of polyvinyl alcohol (PVA) is (C2H4O)n, where n represents the number of repeating ethylene (C2H4O) units in the polymer chain.
Which one of the following formulas represents an aldehyde a c6h10o5 b c2h4o c c2h5oh?
