Question:
Which of the following molecules has a linear shape?
Which of the following molecules has a linear shape?
Show Hint
Key Fact: A molecule with two bonded atoms and no lone pairs on the central atom is linear.
Updated On: May 28, 2025
- H\(_2\)O
- CO\(_2\)
- NH\(_3\)
- SO\(_2\)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
- The shape of a molecule is determined by the VSEPR theory.
- CO\(_2\): Carbon is bonded to two oxygen atoms with no lone pairs on the central atom → linear geometry.
- H\(_2\)O: Bent shape due to 2 lone pairs on oxygen.
- NH\(_3\): Trigonal pyramidal due to 1 lone pair on nitrogen.
- SO\(_2\): Bent shape due to lone pair on sulfur.
