1) Total number of electron paire= (1)/(2) (number of valence electrons pm electron (for ionic charge) 2) Number of bond electron pairs= number of atoms - 3) Number of electron pairs around central atom= total number of electron pairs - 3 [number atoms (except H)] 4) Number lone pair = (number of central electron pairs - number bond pairs) Read the above method and answer the following questions : Based on the given structure of the some of the molecules have been matched. Which is the incorrect matching ?
