What covalent bond is the longest?

Answer 1

The bismuth-iodine single bond is the longest covalent bond that I could find.

Bond lengths are arranged as follows: single > double > triple.

We examine atoms in the lower right corner of the Periodic Table because the largest atoms are expected to form the longest covalent bonds.

Here are Pb, Bi, and I as the most likely candidates.

The bond lengths in the experiment are:

Pb-I = 279 pm, I-I = 266.5 pm, and Bi-I = 281 pm.

Thus, the longest covalent ever measured is the polar covalent Bi-I bond.

Typically, molecules with carbon-carbon (C-C) bonds have the longest covalent bonds.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
