The shapes of water, ammonia, carbon (iv) oxide and methane are respectively
- linear, tetrahedral, angular and pyramidal
-
angular, pyramidal, linear and tetrahedral
- pyramidal, linear, tetrahedral and angular
- tetrahedral, angular, pyramidal and linear
The correct answer is: B
Explanation
Ammonia \((NH_3\)) has a trigonal pyramidal structure with a bond angle of approximately 107 degrees. Methane (\(CH_4\)) has a tetrahedral structure with a bond angle of 109.5 degrees. Carbon dioxide is a linear molecule, with a 180-degree bond angle. Water \((H_2O\)) has a bent or V-shaped structure with a bond angle of approximately 104.5 degrees.
