Question

Give reason for varied bond angle of ch4 h20 and nh3 molecule

Answer 1

CH4 forms tetrahedral shape, H2O forms bent shape and NH3 forms trigonal pyramidal shape... It's main reason is the repulsion force exerted by the lone pair of valence electrons of the central... All the three have different no. of lone pairs which gives different repulsion and hence forms different shapes... which results in different bond angle

Answer 2

varied bond angle is due to lonepair - bondpair repulsion. the structural detail is above...
