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
Correct answer is B
Ammonia (NH3) has a trigonal pyramidal structure with a bond angle of approximately 107 degrees. Methane (CH4) 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 (H2O) has a bent or V-shaped structure with a bond angle of approximately 104.5 degrees.
