![]() Thus, the HgCl2 lewis structure has linear molecular shape and linear electron geometry. They all are connected to each other with single covalent bonds and comes under AX2 generic formula of VSEPR theory. Therefore, the HgCl2 lewis structure has Cl-Hg-Cl bond angle of 180 degree.īond angle of HgCl2 lewis structure HgCl2 hybridizationĪs the HgCl2 lewis structure composed of three atoms i.e. ![]() Hence, the bond angle of HgCl2 is 180 degree. Thus, HgCl2 lewis structure has linear molecular shape and linear electron geometry.Īlso the HgCl2 lewis structure has ‘sp’ hybridization. HgCl2 lewis structure comes under AX2 generic formula of VSEPR theory as the central Hg atom gets linked with two bonding Cl atoms. Hence, as per the VSEPR theory, the HgCl2 lewis structure has linear molecular shape and linear electron geometry. ![]() There is no lone pair electrons present on central Hg atom. Thus, with accord to VSEPR theory, the HgCl2 lewis structure consists of AX2 generic formula in which A is central atom and X is bonding atoms connected to central atom. The HgCl2 lewis structure is a triatomic molecule, composed of one mercury and two chlorine atoms in which the central mercury atom connected with two chlorine atoms. Hence, the resonance structure of HgCl2 is not possible. There are only two single sigma covalent bonds are present on HgCl2 lewis structure.Ĭhlorine atoms have lone electron pairs but sill movement of electrons are not possible to form double or triple bond and also there is no formal charge is available on HgCl2 lewis structure. In HgCl2 lewis structure all these conditions are not fulfilled. Therefore, the Mercury atom and Chlorine atoms in HgCl2 lewis structure has zero formal charge. Thus, in HgCl2 lewis structure the chlorine atom has zero formal charge. Thus, in HgCl2 lewis structure the mercury atom has zero formal charge.Ĭhlorine atom: Chlorine atom has Valence electrons in HgCl2 = 07Ĭhlorine atom has Non- bonding electrons in HgCl2 = 06Ĭhlorine atom has Bonding electrons in HgCl2 = 02 (one bond = two electrons)Ĭhlorine atom of HgCl2 lewis structure has formal charge = (7–6–2/2) = 0 Mercury atom of HgCl2 lewis structure contains formal charge = (02–00–4/2) = 0 Mercury atom has bonding electrons in HgCl2 = 04 (one bond = 2 electrons) Mercury atom has non-bonding electrons in HgCl2 = 00 Let us calculate the formal charge on HgCl2 lewis structure:Īdvertisements Mercury atom: Mercury atom has valence electrons in HgCl2 = 02 The evaluation of formal charge present on HgCl2 lewis structure can be done by evaluating the formal charge present on each Hg and Cl atoms present in HgCl2 lewis structure. There is a formula to evaluate the formal charge present on any lewis structure:įormal charge = (valence electrons – non-bonding electrons – ½ bonding electrons) If the formal charge is present on lewis structure, the lewis structure considered to be a stable lewis structure. The stability of any lewis structure depends upon the formal charge present on it. Therefore, the HgCl2 lewis structure has total six lone pair electrons. Each chlorine atoms contains three lone electron pairs on HgCl2 lewis structure. Here, these 12 non – bonding electrons on two Cl atoms are being six lone electrons pair. The remaining 12 valence electrons are being non – bonding electrons on two Cl atoms of HgCl2 lewis structure. From them four electron are bond pair electrons forming two Hg-Cl bonds within central Hg atom and two bonding Cl atoms. HgCl2 lewis structure has 16 total valence electrons. Octet rule on HgCl2 lewis structure HgCl2 lewis structure lone pairs Finally, predict the shape and geometry of HgCl2 lewis structure with its hybridization and bond angle.Check whether the Hg and Cl atoms have complete or incomplete octets in Hg Cl2 lewis structure.Note the number of lone electrons present on HgCl2 lewis structure.After forming bonds within Hg and Cl left over valence electrons should get put on the bonding Cl atoms and they are being non – bonding electrons.Most electronegative atom will be the central atom and rather all are bonding to it by forming sigma covalent bond within Hg and two cl atoms.Then count the total valence electrons in available on Hg and Cl atoms.Firstly note the positions of groups of Hg and Cl atoms in periodic table.Lewis structure can be drawn with the help of following points listed below: It has some synonyms like sublimate, mercury (ii) chloride, mercury bichloride and Dichloro mercury. It is a triatomic molecule consists of one mercury atom and two chlorine atoms linearly. ![]() Mercuric chloride (HgCl2) is a white solid crystalline powder with no odour. Here, we are discussing about HgCl2 lewis structure, characteristics and quick facts. HgCl2 is the chemical formula of mercuric chloride.
