Are the bonds ionic,nonpolar covalent, or polar covalent? Arrange the substanceswith polar bonds in order of increasing bond polarity: S8 SCl2 RbCl F2 PF3 SF2 Are the bonds ionic,nonpolar covalent, or polar covalent? Arrange the substanceswith polar bonds in order of increasing bond polarity: S8 SCl2 RbCl F2 PF3 SF2
Explanation / Answer
S8 : ring of sulfur; each sulfur has 2 single bonds and 2 lonepairs; nonpolar covalent (only london forces) SCl2: 2 bonds and 2 lone pairs (bent like water): polarcovalent SF2: 2 bonds and 2 lone pairs (bent like water): polar covalent RbCl: (one metal and one nonmetal): ionic F2: simple diatomic: nonpolar covalent Polar bonds: SF2
