Double covalent bond- consists of two pairs of shared electrons. Examples: O 2, CO 2 and H 2 CO (formaldehyde) are molecules that contain double bond. c. Triple covalent bonds- consist of three pairs of shared electrons.
N and As have 5 valence electrons. they need to gain/share 3 electrons to satisfy octet rule. Therefore, a triple bond is needed. Br has 7 valence electrons. Only one electron is needed for it to satisfy octet rule. It just needs a single bond (covalent). Se has 6 valence electrons.
