How can decide which triatomic molecules are linear of the following ?

1.	How can decide which triatomic molecules are linear of the following ? H_(2)O, F_(2) O, BeH_(2), BeCl_(2) , H_(2)S, CO_(2)
Answer» Solution :`BeH_(2), BeCl_(2) , CO_(2)` are linear. Experimentally its dipole MOMENT is zero so DECIDE that these TRIATOMIC MOLECULES are linear.
