Bond angle is the angle which is formed between three atoms across at least two bonds. This angle is different for different compounds.Complete step by step answer:We know bond angle is the angle which is formed between two bonds. It depends on many factors which are stated below:Forces of attraction or repulsion between atoms of molecules may increase or decrease the bond angle.Hybridization also affects the bond angle. As the s character of hybrid orbital increases bond angle increases. Electronegativity and lone pair also affects the bond angle. Increasing the lone pair and decreasing the electronegativity decreases the bond angle.As stated above more the number of lone pairs less is the bond angle due to lone pair-lone pair repulsions. Nitrogen usually makes $3$ bond pairs. In $NH_4^ + $ nitrogen has $4$ bond pairs, this fourth bond nitrogen is made with its lone pair. This means there is no lone pair available in $NH_4^ + $. We know less the number of lone pairs more is the bond angle. So the bond angle of $NH_4^ + $ will be the largest. In $N{H_3}$ nitrogen have three bond pairs and one lone pair and in $NH_2^ - $ nitrogen is having only two bond pairs. This means the number of free electrons in $NH_2^ - $ is more than the number of free electrons in $N{H_3}$ (as there are three bonds of nitrogen normally). This means the bond angle of $NH_2^ - $ will be less than that of $N{H_3}$ (as stated above more the number of lone pairs less is the bond angle. So the order of the bond angle will be: $NH_4^ + > N{H_3} > NH_2^ - $Correct answer is option B that is $NH_4^ + > N{H_3} > NH_2^ - $.Note:Factors which affect bond angle of a molecule are electronegativity, lone pair, hybridization, Forces of attraction or repulsion. Lone pair lone pair repulsions are stronger than lone pair bond pair repulsions and these are stronger than bond pair bond pair repulsions.Recently Updated PagesWho among the following was the religious guru of class 7 social science CBSEwhat is the correct chronological order of the following class 10 social science CBSEWhich of the following was not the actual cause for class 10 social science CBSEWhich of the following statements is not correct A class 10 social science CBSEWhich of the following leaders was not present in the class 10 social science CBSEGarampani Sanctuary is located at A Diphu Assam B Gangtok class 10 social science CBSEWho among the following was the religious guru of class 7 social science CBSEwhat is the correct chronological order of the following class 10 social science CBSEWhich of the following was not the actual cause for class 10 social science CBSEWhich of the following statements is not correct A class 10 social science CBSEWhich of the following leaders was not present in the class 10 social science CBSEGarampani Sanctuary is located at A Diphu Assam B Gangtok class 10 social science CBSE
