EXAMPLE 3.5 HCP, like HCN, is linear, with a triple bond: H-C=P: IOF,- has a single lone pair on the side opposite the oxygen. The lone pair has a slightly greater repulsive effect than the double bond to oxygen, as shown by the average 0-I-Fangle of 89°. (The extra repulsive character of the I=0 bond places it opposite the lone pair.) SEOCI, has both a lone pair and a selenium-oxygen double bond. The lone pair has a greater effect than the double bond; the Ci–Se-Cl angle is reduced to 97° by this effect, and the Cl-Se-O angle is 106°. EXERCISE 3.3 Predict the structures of the following. Indicate the direction of distortions from the regular structures. XEOF, CIOF; SOCI,
