This type of torch is used to cut and weld steel, and it uses acetylene as fuel. The shared electrons are pulled closer to the more electronegative atom, making it slightly negative and the other atom slightly positive. Although it has an asymmetrical molecular geometry, the entire molecule is non-polar dues to the absence of any polar bonds. Thus, the sulfone was rapidly deprotonated in THF/DMPU (3: 1) at -78 °C and quenched with chloroiodomethane, affording a 5:1 mixture of chloromethylene sulfones, which was immediately subjected to a sodium amalgam reduction. (c) NH3: Hydrogen Bonding dominates (although there are dispersion and dipole-dipole forces too). hydrogen atom in a polar bond and nonbonding electron pair on a nearby small electronegative ion or atom (usually F, O or N).
