C2h5 o c2h5 carbon, single bond carbon single bond carbon single bond carbon hydrogen, hydrogen, hydrogen hydrogen this is a game with hydrogen hydrogen, nitrogen hydrogen, nitrogen nitrogen this is termed as a and this is termed as b a, carbon single bond hydrogen here, carbon is having minus 3 and hydrogen having plus 1 ca is equal to minus 3 2ca will become minus 3 multiplied by 2 that is minus 6 carbon hydrogen oxygen hydrogen minus 2 plus 2, oxygen is having minus 1 cb is equal to minus 2 plus in bracket plus 2 that is equal to 0 carbon is equal to minus 3 plus 0 minus 6 carbon is equal to minus 6 divided by 4 that is equal to minus 1 .5 next, we have hcooh carbon, double bond oxygen, single bond hydrogen, single bond hydrogen, minus 2 plus 1, plus 1, oxygen is equal to minus 2 oh is equal to minus 1, h is equal to plus 1 plus 2, plus plus 1, plus in bracket minus 1 divided by 1 that is equal to 2 next, we have ch3cho that is carbon, single bond hydrogen, single bond carbon, double bond oxygen, single bond hydrogen this is termed as a this carbon is termed as b hydrogen is having plus 1 charge oxygen is having minus 2 a is equal to carbon, single bond hydrogen, carbon is having minus 3, hydrogen is having plus 1, plus 1, plus carbon is equal to minus 3 in a, in b carbon, double bond oxygen single bond hydrogen oxygen minus 2 hydrogen plus 1 carbon plus 2 minus 1, carbon b is equal to plus 1, so c is equal to minus 3 plus 1 divided by 2 that is equal to minus 1.

Next, we have methane here all hydrogen is having plus 1 charge and carbon minus 2, minus 1 multiplied by 4 that is equal to minus 4 in carbon hydrogen bond the hydrogen is treated as if it has oxidation state of plus 1 4 hydrogen is equal to plus 1 multiplied by 4 that is equal to plus 4 that is carbon oxidation number is equal to minus 2...
