Answer:
So, 2 1
3
Explanation:
Carbon is a non-metal and has 6 electrons. In the excited state, it contains 4 electrons in its outermost shell and so 4 electrons take place in covalent bond formation. In a molecule , 2 carbon atoms can be bound by a single bond, the double bond and by a triple bond. Since the bond length of is 120 pm, the bond length of
is 134 pm and the bond length of
is 154 pm. Thus in the given compound,
, in which
is labeled as 1,
is labeled as 2 and
is labeled as 3. So the bond length of carbon-carbon bonds in the molecule, in decreasing order is
.
