The length of double bond is _______ than single bond. A. Shorter B. Longer C. Of same lenght D. None of the above

The correct answer is: A. Shorter.

A double bond is shorter than a single bond because the two atoms in a double bond are held together by two pairs of electrons, while the two atoms in a single bond are held together by only one pair of electrons. This means that the electrons in a double bond are shared more strongly between the two atoms, which makes the bond shorter.

Option B is incorrect because a double bond is not longer than a single bond. Option C is incorrect because a double bond is not the same length
