Answer 1

Covalent bond distance is defined by the internuclear distance between two covalently bonded atoms and is denoted by d. It can be used as a measure of the strength of a bond and can be measured for bonded atoms that have any bond order (not just singly-bonded atoms, as is the case of rcov). Values for Covalent bond distance are determined by X-ray, electron and neutron diffraction, as well as by microwave spectroscopy. Though d is the most commonly measured value, rcov is more commonly used (see next section below). d is measured in picometers (1pm=10-12m) and ångströms (1Å=10-10m). Covalent bond distance can be used as a measure of how tightly two atoms are bonded and is often used to support calculations of bond order. Typically, the higher the bond order, the shorter the Covalent bond distance.
