Identify the incorrect statement from the following :

Step-by-step solution

Carbon has a strong tendency to form p - p multiple bonds with itself, such as in alkenes and alkynes. Thus, the first statement is correct. BCl ₃ exists as a monomer because boron cannot expand its octet to form a dimer, whereas AlCl ₃ exists as a dimer ( Al ₂ Cl ₆ ) to complete its octet. Thus, the second statement is correct. The catenation property depends on the element-element bond strength. The bond enthalpy decreases down the group, so the order of catenation is C >> Si > Ge Sn . Thus, the third statement i
