This is a very fundamental question in the field of molecular chemistry. Lets see how to do it. What is the Name the binary molecular compound NI3? A:Phosgene or Cl2CO , is a non-flammable acutely toxic gas. Q:he structure of 1,2-propadiene (allene) is shown to the right. A covalent bond is formed when non-metal atoms share their valence electrons, which they do in order to achieve filled valence orbitals like their nearest noble gas neighbor. Because the center atom, carbon, has two C-H and C-Br bonds with the hydrogen and bromine atoms surrounding it. Since both carbon central atom is bonded with three atoms(one hydrogen, one chlorine, and one another carbon) and it has no lone pair which means, it is an AX3 type molecule which implies its geometry will be trigonal planar. If there are any lone pairs, describe what type of orbital contains these electrons. A:The given molecule is propane and it has the molecular formula CH3-CH2-CH3. Predict the hybridization, geometry, and bond angles for the carbon atoms in acetylene, C2H2. The atom with the lower electronegativity will have bond electrons pulled further away from it, causing it to obtain a very slight positive charge (\(\delta ^+\)). sp3 ------> tetrahedral.
