Question 1 Report

Which of the following molecules has a linear shape?
Answer Details
A molecule is linear if all of its atoms lie in a straight line. Of the given molecules, only CO2 has a linear shape because it has a central carbon atom double-bonded to two oxygen atoms, which are both linearly arranged on opposite sides of the carbon atom, forming a straight line. CH4, H2S, and NH3 have a tetrahedral, bent, and pyramidal shape respectively, meaning they are not linear.
