Question

carbon - carbon single bond length is higher than carbon- carbon double bond length​

Answer 1

Explanation:

carbon carbon single bond length is higher than carbon carbon double bond length because length of single bond is always more than length of double bond

length =single bond> double bond> triple Bond

Answer 2

Double bond is more stronger than single bond because, Bond length in double bond is 1.34 angstrom while in single bond is 1.54 angstrom where bond length is inversely proportional to bond energy so less bond length, more bond energy is required to break thus it is more stronger bond.
