Answer to Question #93127 in General Chemistry for Nduduzo

Question

Which of the following attain the linear structure?
A. CS2
B. NO2
C. BeCl2
D. NCO+

Answer 1

The answers are A, C and D, because:

• there are two sulfur atoms bonded to a central carbon atom and the central atom has no lone electron pairs

nitrogen dioxide has an unpaired electron so it isn't a linear molecule

beryllium chloride is linear (central atom has no lone electron pairs)

• studies suggest (https://sci-hub.se/10.1063%2F1.1711597) that a NCO cation is linear, but it will be better if you check your textbook
