PbI4 doesn't exist and converts into PbI2 and I2 spontaneously at room temperature but PbCl4 needs h — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Nitrogen dioxide (NO2) is an odd-electron bent molecule. Step 2: The central Nitrogen atom forms two sigma bonds and holds a single odd electron in a hybridized orbital. The total steric number is 3 (2 sigma bonds + 1 odd-electron domain). Step 3: A steric number of 3 corresponds to sp2 hybridization of the Nitrogen atom, which is option (b).
