Three outer atoms and one lone pair surround the central atom. document.getElementById( "ak_js" ).setAttribute( "value", ( new Date() ).getTime() ); This site uses Akismet to reduce spam. A:The degree of halogen is determined by the degree of carbon to which halogen is attached. In the CH2Br2 molecular geometry, the C-Br and C-H bonds have stayed in the four terminals of the tetrahedral molecule. The Lewis structure drawn in the above section is the most appropriate because it satisfies the octet rule and formal charges. There are two lone pairs of electrons on each Oxygen atom; thus, there are four lone pairs of electrons for H2O2. The bound pairs (C-H and C-Br) of electrons to the core carbon atom are represented by X. To find : Bond line structure of the Compound with proper hybridization, Q:Which of the following contains sp-hybridized carbon? A:Formula for determining the hybridization of central atom :- In the very first step, we will count the total valence electron in the C2H2Cl2 molecule.
