As electronegativity of P is much lower than N, so in NH3 nitrogen attracts all bond electron towards the centre and electron-electron repulsion is higher so it has a higher bond angle. Bond angle in ammonia is 107 & that in phosphene is 93.5.

Q5
Assertion :Bond angle in NH3 is greater than that in PH3. Reason: P−H bonds are longer the lower electronegativity of P permits electron density to be displaced towards H to a greater extent than in the case of NH3.
