Question

The number of molecules/ions that show linear geometry among the following is ________ .

\(SO_2,BeCl_2,CO_2, N_3 ^- , NO_2, F_2O, XeF_2, NO_2 ^+, I_3 ^-, O_3\)

Answer 1

Answer is: 6

Linear species are

\(\underset{\underset{(sp)}{}}{Cl - Be -Cl,}\)  \(\underset{\underset{(sp)}{}}{O=C=O,}\)  \(\underset{\underset{(sp)}{}}{N^- = N^+ = N^-}\)
