Solution
Solution:
VSEPR Theory:
Electron pair around the central atom repel each other and move so far apart from each other that are no further repulsions between them. As a result, molecule acquires minimum energy and maximum stability.
Analyzing options
\((A)~BeCl_{2}\rightarrow~Cl~-~Be~-~Cl,\) Linear structure
\((B)~NCO^{+}~\rightarrow~N~\equiv~C~-~O^{+},\) Linear structure
\((D)~CS_{2}~\rightarrow~S~=~C~=~S,\) Linear structure
\(BeCl_{2},~NCO^{+}~\text{and}~CS_{2}\) have linear structure.
Hence, correct options are (A), (B) and (D).
