(A) 5 covalent bonds (B) 12 covalent bonds (C) 16 covalent bonds (D) 17 covalent bonds For example, O2 is double bonded because there are 12 valence electrons and oxygen can form 2 covalent bonds, so the presence of these 2 bonds with 4 additional valence electrons per oxygen totals 12 electrons. H2S or hydrogen sulfide has a bent structure. In contrast, silicon in group 14 has little tendency to form discrete silicon–oxygen double bonds. A double bond in chemistry is a covalent bond between two atoms involving four bonding electrons as opposed to two in a single bond.Double bonds occur most commonly between two carbon atoms, for example in alkenes.Many double bonds exist between two different elements: for example, in a carbonyl group between a carbon atom and an oxygen atom. The S is the central atom, with single bonds to both H atoms. You name them like ordinary alkenes, but with the ending -diene.

Each chlorine is singly-bonded to the central carbon and each chlorine also features 3 lone pairs (6 total electrons). The double bonds are shorter and much stronger than single bonds. The equal sign is used to indicate a double bond in a formula. Double bond forms when two atoms share two pairs of electrons between them to fill the valence orbitals. I would have said "No, it can't be chiral because chirality (stereochemistry) only applies to carbons that are attached to 4 different substituent group (4 sp3 bonds)" until my class 10th. Russian chemist Alexander Butlerov introduced double bonds … Stack Exchange Network. Pentane has the molecular formula C5H12.
