14) Los siguientes valores de ángulos y longitudes de enlace se obtuvieron experimentalmente para los iones IOs, CIOs y Bros. Indique a cual ión corresponde cada grupo de datos. Dé una explicación para su selección (6 ptos) X-O (pm) O-X-O (ángulo) 149 1070 1040 100 Dar el nombre recomendado para las siguientes sustancias: 1203 FeH2 HCI (9) HCI (ac) Pb(OH), H3POs HCIO BaO2 H2SeO2 Pb(SO3)2 Ca(CIO)2 Pb(HSO )4 Na2O2

Answer 1

April '09 I Oz - Diiodine Trosside Thunday Fette - Ferrous hyderide Halg - Hydrogen Chloride gas Hal (aq) - Hydrochloric acid. Pb(OH)4 - Lead (1) hydroxide H₂ POz - Hypophosphorous acid Halo - Perchloric acid BaO₂ - Barium (11) peroxide H,sed - Selemnic Acid. Pb (503) - tead (II) sulphite. Calcio)2 - Calcium(D) hypochlorite.

Monday Bond length Bond 149pm cloe 107° Broge - 165pm 181pm 104° 100 20,0 Boud length of 10 is greater. This is because I size is greater than other halogens Bond length of 40 is minimum. because, size of ae is least. Bond angle of coo is maximum. This is because, ce is the most electronegetive atóm among these three Abelief is not true because it is liseful

April '09 Tuesday Layanthi lndial. Women's Day Mozambiquel, Heroes' Day Tanzania So, a o bond electron density will be concentrated mainly on a. This results a repulsion in relectron density and expansiggs in bond angle. Besides, there is a pu-dit boock bonding between a vacand 3d orbital of ca and fullfilled ap orbital of o. This does not happen in other cases. I is least electronegetive. So, electron density on I is least and bond angle is also lowest- mm.
