A.
linear, tetrahedral, angular and pyramidal
B.
angular, pyramidal, linear and tetrahedral
C.
pyramidal, linear, tetrahedral and angular
D.
tetrahedral, angular, pyramidal and linear
Correct Answer: Option 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.
