Solution
The correct option is C Ethylene
∙ In ethylene (CH2=CH2) molecule, a double bond is formed between two sp2 hybridized carbon atoms.
∙ Each carbon atom in ethane (CH3−CH3) and propane (CH3−CH2−CH3) is sp3 hybridised.
∙ An acetylene molecule (CH≡CH) contains two sp hybridised carbon atoms with a triple bond between them.
The given table shows the molecular formula and total number of sigma bonds present in the compound.
