The number of hydrogen atoms present in the following compound are:
Carbon has a valency of 4.
∙ If a single bond is formed by a carbon atom with a carbon atom, then 3 remaining valency are occupied by hydrogen atoms.
∙ If two single bonds are formed by a carbon atom with two other carbon atom, then 2 remaining valency are occupied by hydrogen atoms.
∙ If a double bonds are formed by a carbon atom with a carbon atom, then 2 remaining valency are occupied by hydrogen atoms.
∙ If a single and a double bond is formed by a carbon atom with two other carbon atoms, then 1 remaining valency are occupied by hydrogen atoms.
Therefore, total number of hydrogen atoms are 10.
