Question

Bond angle and shape of h2o, nh3, ch4, c2h2, c2h4

Answer 1

•H2O forms a bent structure because it has 2 lone pairs over O Atom.So the bond angle would be 104.5°

•NH3 forms a pyramidal structure because it has 1 lone pair. So the bond angle would be 107°

•CH4 forms a tetrahedral because it has no lone pair.So the bond angle would be 109.5°

•As C2H2 is SP hybridized , so the bond angle would be 180°

•and C2H4 has a trigonal molecular geometry so the bond angle will be about 120°.
