Question

1. hydrogen is a strange atom. while it has just one electron in its valence shell, it usually forms covalent, rather than ionic bonds. propose a justification for this phenomenon.
2. an atom has two bonds. the bond lengths are measured in angstroms (a). one bond is 1.5 a in length. the other bond is 1.2 a. which bond is a single bond, and which bond is a triple bond?

Explanation:

Step1: Understand bond length and bond type relationship

Bond length is inversely related to bond strength and bond order. Triple bonds have a higher bond order (3) compared to single bonds (bond order = 1). Higher - order bonds are stronger and shorter.

Step2: Compare the given bond lengths

We are given two bond lengths: \(1.5\mathring{A}\) and \(1.2\mathring{A}\). Since triple bonds are shorter than single bonds, the shorter bond (\(1.2\mathring{A}\)) is the triple bond and the longer bond (\(1.5\mathring{A}\)) is the single bond.

Answer:

The bond with length \(1.5\mathring{A}\) is a single bond and the bond with length \(1.2\mathring{A}\) is a triple bond.
