Vedclass · Answer

(D) $A)$ $BeCl_2$ is a linear molecule in the vapour state ($sp$ hybridization) and polymeric in the solid state. This statement is True.$B)$ $BeO$ is amphoteric,but $CaO$ is basic. Therefore,the statement that both are amphoteric is False.$C)$ $CaC_2$ reacts with water to form acetylene $(C_2H_2)$,but $Be_2C$ reacts with water to form methane $(CH_4)$. Therefore,the statement is False.Since both $(B)$ and $(C)$ are false,the correct option is $(D)$.
